MKS Gen L + 2x Mosfets

MKS Gen L holder with 2 external Mosfets and Cover with Fan hole (60mm & 40mm)

This model works so far quite well is however still not perfect!

A closed holder for the MKS Gen L with ventilation slots for the stepper drivers. all cutouts for for example USB and display cables are available. all cables for endstop switches and the similar can be taken out on the display cable page.

The Mosfets are not closed because most external mosfets don't get hotter than room temperature and I had no desire to make the closed case so big (save filament and printing time). Furthermore you can wire the mosfets directly and only have to lead the control cables and the board supply through the hole.

The whole thing will be held on 3030 aluminium profiles (standard M6 with hammer nut) but will fit for 2020 too.

For the MKS gen l there are matching screw holes available. unfortunately the holes are a bit too big for M3 screws (3,2mm), but some glue should help or longer screws and melt the screws into the plastic.

As mosfets i used the "3D friends v2" from amazon and adjusted the holes accordingly. If you are interested in other mosfet sizes, I can also adjust them. Holes are the same size here.

The cover is available in 2 versions, one for 40mm and one for 60mm fan. The 60mm works quite well for me and can be printed without support upside down, but the airflow is not perfect here. The 60mm version also has a bigger hole for the fan plug.

The 40mm version can also be printed without support and should bring enough cooling. The 40mm version was only made because I thought the fan I had left would be 40mm big.

Additionally there are 3 holes on the inside to fix the Ramps Fan extender or other additional things.

The whole component doesn't extend a millimetre over the 3030 profiles, so it shouldn't stand in the way of any other part such as the x motor holder.

Update: The raise for the screws seems not to be deep enough, but with a soldering iron you can just push the screws in a little bit.

I printed the design and my printer has been running for several months without problems

Pictures will follow in the future

Edit: no pictures. Too ashamed of my messy wiring
