SKR 1.3 enclosure mounts to 2020 or 2040 aluminum extrusions for 4010 or 4020 cooling fan

thingiverse

I really liked this enclosure design, so I decided to modify it to fit perfectly with 2020 extrusions by adding some mounting holes. The big ventilation slots on the top cover didn't appeal to me, so I added smaller ones in the bottom shell and offered several alternative options. To keep the enclosure cool, I opted for a 4020 fan and made that an available choice. The original model's walls are 2mm thick, which provides sufficient rigidity for most applications but does have some give. To address this concern, I added options with thicker bottoms and thicker mounting-side walls, offering more stability for those who need it.
