damn all of us out here wasting money on buying these when we could make these instead! I feel scammed.

It's not a waste to support the development the E3D guys put into their products. They've done a lot of cool stuff and came up with a lot of good ideas that wouldn't have been without people buying their stuff.

As far as this particular model, I made it because there wasn't one that existed for the CR-10 yet that I could find

I mean this is for the cr-10. I got my silicone sock from tiny machines.

ooh got a link? I'd love to see what they're doing

It's high quality don't get me wrong, your method just seems cheaper. plus you don't have to wait for shipping. https://tinymachines3d.com/collections/awesome-upgrades/products/mk10-silicone-sock

most definitely cheaper, definitely faster, but also messier which is a downside.

Also I'm still searching for a slightly more rigid kind of silicone than the RTV as it seems to expand and sweats some kind of fluid at higher temperatures (240C+)

Let me start out by saying your design is awesome! Instead of the printed nozzle tip, would it better to make a M3 screw hole from the bottom into the insert? I think it would both clamp the parts together and act as a centering pin to ensure proper alignment. Either way, thanks for your hard work.

Without the nozzle tip part, you'd miss out on the part of the sock that prevents filament from building up on the nozzle.

Using a screw on the nozzle tip isnt a bad idea though, but I'd probably need to use a smaller one than an M3 as the aperture for the tip of the nozzle is much smaller than that.

As far as alignment goes, currently, as long as the insert is screwed into the handle firmly with the cap between them it's been pretty well lined up. the other problem I can see coming from the screw on the bottom is that it would be a way way messier assembly since you'd have to screw the insert into the shell while the silicone was already in there (otherwise you'd have more gaps under it)

Anyhoo, thanks for the suggestion, and I'll see what improvements I can make

Do you know if it's the same heatblock on the Ender 2?

Looks about the same as the TronXY X1 as well

I'm 99% sure the ender 2 and TronXY are clones, and are using the same hotend as the other Creality series

I can't tell for sure from the pics online, but it does look very similar. If it's not, and you can provide measurements for me, if be happy to make one for that printer
