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

thingiverse

I really liked this enclosure design, but i wanted to mount it to 2020 extrusions so i added some mounting holes. I didn't like the big ventilation slots on the top cover, so i added ventilation slots in the bottom shell and added several different options. I wanted to use a 4020 fan to cool the enclosure so i made an option for that as well. The walls in the original model are 2mm thick which is rigid enough for my application and probably for most applications, but it does have some flex. I added some options that have a thicker bottom and thicker mounting-side wall that should offer more rigidity for people that are concerned about that.
