can i remix that for marui hi capa 4.3?

HCC-2A is live as of... like a few days ago! https://www.thingiverse.com/thing:3712294

Please consider downloading and printing the HCC-2A rather than this kit - the HCC-A2 is a LOT more refined, and is the "ultimate" version of this kit.

JTW HCC-2A (An Open-Source Hi-CAPA Carbine Kit)

July 1st release date is go. Modelling of the V2 kit and a printed rough have been completed. Giving myself some breathing room before release in case I missed anything.

Comments deleted.

Hey all,

Figured a V2 update was in order after some significant progress today.

First of all, I'd like to thank everyone who has continued to be interested in this project despite no real changes yet. I've been hard at work finishing up the V2 model - which is, in all regards, a SUBSTANTIALLY better design - and I'm finally at the point where I am test printing it.

What is taking so long?!:
My printer has been a piece of shit lately. Thankfully, with the recent release of Creawesome, I've been able to tighten up my prints DRAMATICALLY. For V2, I wanted to be SURE that everything fits before I put up the files, as I had to iterate on the V1 several times based off of some feedback.

What is V2?:
See the attached image for a visual reference. The V2 is stylistically and functionally an improvement on the design of V1, with the aesthetic design based off of a concept I made over a year and a half ago. It retains the forward-oriented ambidextrous charging handle of the V1, though the guides on the charging handle have been made significantly more durable and resilient (enough that it can, in fact, be safely printed from PLA and abused - like the REST of V2!). The internal dimensions have been refined so they don't block the slide release (an existing problem with V1) and the trigger guard has been overhauled so it doesn't interfere with the trigger guard on your HiCapa. In addition, there is now a secondary magazine retainer built into the receiver. This provides a "factory"-supplied angled foregrip, while allowing storage for another magazine. This only retains passively through friction at the moment, but later down the road, I intend to have this use active retention, much like your existing magazine release (because of this, I've designed the magazine retainer as an independently-printed component, so when the revision with active-retention is available, it will be a simple conversion of your original V2 kit). V2 will also be compatible with AEG M4-style buffer tubes and any supported style of stock.

When and where will it be available?:
I am expecting to release the final build of V2 here on Thingiverse on July 1st, 2019. Rather than completely replacing the V1 files or making a huge mess of the Thingiverse file tree for V1, I will be releasing it separately as its own different upload on Thingiverse. If you'd like to be alerted to it immediately when it's uploaded, you can follow me here. Additionally, I will be printing and selling kits through Etsy for those who don't have a printer capable of the job or just want to buy one instead of building one. These will initially be available in a low quantity for a short time to gauge interest. You can also email me at jokertoolworks@gmail.com if you would like to place a pre-order hold so you're one of the first to get a kit (no down payment required, simply say you'd like a hold and I'll email you when one is available for purchase). Pricing is still under consideration, but expect between $60-$120 depending on colors, materials, customizations, and so on.

Can I print the V1 and V2 kits and sell them myself?:
Yes! This project is fully open-source. I initially wanted to start this project because the market for carbine kits was so small, and I had an idea that it would be very interesting to see several different people selling these at varying levels of quality, pricing, and materials/medium used for production. All I ask is that if you DO print and sell them yourself, or even have a printing farm produce a bunch for you to sell, you link back to my Thingiverse post for the item in your description and credit those involved in your listing for the design.

Will I be able to print this on my 165x165mm printer?:
Unfortunately, no. While I've done my best to split the file up into reasonable chunks, you will need a printer with at least 230mm of Z clearance, as well as 160mm of clearance on the X and Y axiis (at least 160mm of diagonal on the bed). This project is built with 300x300mm (or at least 300x220mm) printers in mind, as they are rapidly becoming more popular and easier to obtain. Other people have expressed interest in uploading remixes designed for smaller printers to handle the job, and that's absolutely fine with me! But for the ones I'm printing, having as many pieces as possible be one solid part is going to be a necessity for durability.

Thanks for your patience!

Hey, man,

Thanks for the design, it's really good work.
So I did it for a Hicapa NOVRITSCH SSP-1 and unfortunately it doesn't fit in.
I printed all the parts on a HP MJF540 so the precision is there and I was able to print the receiver in one piece.
It is the replica in itself that is too wide, the rail is placed differently and is longer than on a TM, you can see on the pictures where I started to remove some material and I will have to remove some under the barrel so for the charging handle to play its role well.

When I finish the modifications on the piece I think I will remix the receiver to make the SSP1 version.

I'll keep you informed.

Oh, sorry about that. This file is meant specifically for TM HiCapa 5.1's, and the SSP-1 is it's own special specs (from what I understand, Novritsch had the pistol designed from scratch, and it mostly forms as a HiCapa for some internal parts compatibility and aesthetic appeal). The sights, slide, and frame are all incompatible dimensions (as you clearly know now). If you could make a remix version, that'd be great! The more compatible options, the better.

If you wouldn't mind, could you provide me with the dimensions you end up changing? I'll be releasing the V2 of this kit within the next month or so (which is a major overhaul) and having an SSP-1 model available for everyone out the gate would be great.

No problem for the dimensions of the SSP1, I will send you annotated photos with the dimensions and I even thought I would remix an existing hicapa to have the dimensions of this replica and thus be able to make the modifications on all the kits and other accessories.

PS: I have seen your picture of the V2 and personally (from my point of view and in all subjectivity) I find that the foregrip/magazine storage is really not necessary and I prefer to have a rail to put the handle / lamp / mini grenade launcher.
I think you should plan in a 2nd time (or at the same time) to make a version without this compartment with just a rail.

We'll keep in touch.

Thanks for the feedback! It's actually quite a simple matter for me to get rid of the extra magazine holder entirely, and that's a good idea for a second available variation. The front end does already have a rail on the handguard for foregrips/lights/etc, but were you thinking that the existing rail should be longer? If I tweak the receiver geometry just a little bit, I could easily double the length of the existing handguard rail.

So for people who have smaller print heights (Like I have) I decided to split the receiver into two pieces and make small holes on one side and rods on the other piece. All you have to do is use some adhesive to join the two together. As long as Craig is happy for me to leave the file on this comment then anyone else who have smaller printers can you it.

Edit: I'll upload it as a remix as well so its more likely to be seen.

Yep, totally fine with you posting that here - good work! Nice to have more options available for the kit.

I'm intending to add a split receiver model to this master here soon as an alternate printing option as well. Hopefully this kit will end up highly refined and easy for people with all sizes of printer to make!

Thank you! When it comes to the stock as well it be worth considering a buffer tube adapter. I'm currently using my old stock off my old Ak which had a non standard connection. I have made a file for it but I haven't finished printing everything to full test everything. Can't wait to see what V2 brings!

Nice design Craig, well done mate

I'll take a look at this kit probably later tonight.

I have a suggestion already for printing the body in two pieces that can be screwed together (its not gorgeous, but it doesnt disrupt the body lines much) but I'll need to do up a demo so you can see. I printed a carbine kit more than twice this size on an ender 3, you just have to split it up smartly like SRU does ;)

Also, as a suggestion, use self-boring magnesium wood/drywall screws with holes to set the rails in. Theyre strong enough to hold with PETG and even PLA+ for heavy attachments (that's how I did my universal carbine kit and can mount a full size M203 on it)

Good work so far though, I like the overall lines and I love the back-side racking mechanism. I have some suggestions for that part too but I think I want to print it as-is to see where the weak points are first, then work on reinforcing it.

If you get some of that stuff concepted out, please upload it as a remix. Your ideas sound interesting and it'd be cool to see people iterate on this. It would also be nice for there to be my version of the kit where it's print everything as one piece, and another version of the kit that's more usable for people with beds smaller than 300x300mm.

For attaching the rails, the V2 I'm working on (it's taking a while because my printer is on the fritz most days) uses M4 screws with nuts sunk into the body, so that will clean up and reinforce the rail installation a bit. The V2 has slightly different body geometry but the concept would carry over to this version just fine, and will eventually get implemented when I have the time.

Yeah will do :) Once I get time to sit down and work on it lol

Its nice being 2 part print as well, because you can make it in to a modular system of pieces like that if you want different back/front halves.

I tried an embedded nut system for something like this but I couldn't find a way to make it not be a PITA to get the nut in or out, and also have it not spin freely when screwing the bolt in, and also not ruining the view of the kit.

But if you prefer instead of me uploading a full remix, I can just email you a file so you can see how I did it and then just download those identical parts or use the same idea in your original.

I ended up just making long hexagonal shafts that fit the M4 nut perfectly. It's easy enough to seat them, though it's probably impossible to get them out without damaging the model, so they would be committed to the project until the person who prints it is "done" with it I suppose.

I was gonna ask if you would be okay with me adding changes you make to the master file, but didn't want to presume. If/when you get the changes you're thinking about done, shoot me a DM and I'll send you an email address to send them to (thingiverse is weird with file attachments ime). Otherwise just post it as a remix, I'm fine with it either way. Thanks!

I just got done with the really basic version of the concept :)

Shooting you a PM now with a tinkercad link.

Unfortunately the receiver is just about 1-2 cm too long to fit on an ender 3 print bed


I had the same problem so I split the receiver. Happy Printing!

Split Hi Capa Carbine Kit receiver

would this work on an elite force 1911 tactical blow back gas air soft pistol

I will try it for my KJW 6.1 Hi capa. One thing though, I didn`t undertand how the charging works. How do I cicle the gun when I inset the mag for the fist time?

When the slide is closed and you insert a new mag, you just cycle the charging handle. When the slide is open and you insert a new mag, drop the slide with the slide catch. Slide catch and the safety are still accessible with this kit.

And this won't fit a 6.1 hicapa. It's meant to fit a 5.1. 6.1 will be too long.

do i have to remove the front site to make this work? im thinking about printing this for my kjw hi capa

So the rear plate of the carbine kit has to be removed to insert the pistol, and then attached once the pistol's been inserted, but that's it. There is space for the sights to move freely through the receiver.

I'll note though that the rear plate isn't essential for functionality, and the mounting system I designed for it doesn't work as well as I'd like, so it may be best to skip that one part when your print it.
