MKS GEN L / RAMPS + DUAL MOSFET CASE (UNIVERSAL & ANET A8 VERSIONS)
Couldn't find a decent "universal" electronics housing for my custom AM8 build that could contain a MKS Gen L V1.0 board with two mosfets, and enough room inside to fit the height of the board with TMC2130 drivers with protection boards, heatsinks and wires, so I remixed an existing one to suite my needs.
Of course it will fit any other driver you might have!
If you're using RAMPS board, I made an adapter that will fit an Arduino Mega 2560 Rev3, so you can use it with any RAMPS kit, whether it's 1.4, 1.5 or 1.6.
Universal version of the base:
It has several 5mm holes all round the base so you can bolt it pretty much how you want on 2020/2040/3030/etc aluminium profiles based frames (AM8, HyperCube, CoreXY, FLSun Cube, Prusa i3 & MK3, Creality CR-10 & CR-10S & Ender 3, TEVO Tarantula & Tornado, etc), personnally I screwed it on the side of my IKEA enclosure, be creative!
Anet A8 version of the base ("A8" in the file name):
It will bolt right in the holes where the motherboard is usually bolted on the acrylic frame using the provided bolts and nuts.
You'll notice both bases come in "low" and "high" versions, the low version is 60mm tall and won't accommodate a fan inside it, if you're using this base you'll have to either not use a fan or mount it outside as it doesn't provide enough clearance with the mosfets, the high version is 80mm tall and will allow you to fit a fan up to 30mm thick inside the case.
There are 4 version of the lid, chose the one that suits you, one is plain if you don't want active cooling, one for a 80mm fan, one for a 120mm fan, and a full honeycomb if you like it (allows you to see what's inside the housing, cools better than the plain version, and you might attach various things on it if you want). Each lid is symetrical so you can screw it upside down if your first layer looks better than your top one.
I also made a Punisher version of the lid for 80mm and 120mm fans that you can find here: https://www.thingiverse.com/thing:3027936
I'll might make different versions of the lid in the future, do not hesitate to ask in the comment if you have an idea, I'll make it and publish it here! :)
In addition to printed parts, you'll need:
- 16x M3x10mm or less screws for MKS board, mosfets and top cover (4x for each)
- 1x 80mm or 120mm fan if you want active cooling (strongly recommended)
- 4x M3x8mm or less screws for RAMPS if you're using the adapter (10mm will be a bit too long but you can us them with washers if you don't have 8mm or less)
Quick video (sorry for bad quality) of the high version with 120mm led fan from AliExpress: https://www.youtube.com/watch?v=zKnEcrpt9uM
Feel free to leave a comment below if you have any question or need anything, I'll have a look asap, also please post pictures if you make one! :)
Supports are usefull for the base's square holes, but if your printer can achieve 70mm horizontal bridge feel free to print without when! :) They are highly recommended if you have any doubt tho, the base was made so they are easy to remove.
Supports are mandatory on RAMPS adapter if you print it.
No support on lid of course, whatever version you chose.
20% infill is enough, feel free to put more if you want extra stiffness.
Ironing can be used on every parts for a super smooth surface finish if your slicer has that function! ;)
2018-05-07 added some cable strain reliefs on each holes, you can attach your cables to them using any zip tie upt to 4mm width.
2018-05-07 added a RAMPS adapter.
2018-05-14 added braces around the screw posts to harden them.
2018-06-08 added braces around the 4 tall posts holding the lid to harden them and a 20x20mm hole near MOSFETs if you want to wire them from there.
2018-06-11 added a version of the base that will bolt right on acrylic frame of a Anet A8 using the motherboard's holes.
2018-06-13 added 3 different versions of the lid in addition to the 80mm fan version (plain, 120mm fan and full honeycomb).
2018-07-04 added high versions of the bases so a fan up to 30mm thick can fit inside the case.
2018-07-24 made higher holes (4mm vs former 2mm) on cable strain relief so that supports are easier to remove if you print with them.
2018-07-29 enlarged the inner A8 holes for easier fitment on the frame.
2018-07-29 made the honeycomb pattern of the full honeycomb lid a bit bolder so it prints more easily.
