Case for MKS Sbase 32 bit controller on my TronXY X5S. The top and the bottom are a snap fit.
This is almost an Art Deco case. The fan guard domes give it that Deco look. There is only one fan inside the case now. But if the need arises - I can quickly add 3 more. I didn't want to leave big holes where things could fall through. (yes, it can still happen) but maybe the curved surface will defect it.
I used my 40mm fan guard dome with retaining pins to attach the 'domes'. https://www.thingiverse.com/thing:3194489
