This is a mini server rack for my elitedesk/prodesk deskmini PC. But the dimension can fit mac mini or other mini pc, network switch etc…

It's assembled using multiple identical part as supports and platforms. 

The mounting hole is 4.6mm in diameter, and the distance is 25mm, which allows you to mount any VESA device with screw.

To assemble the platform together, you will need 4pieces of 20mm m.4 bolts and nuts for each platform you want to add.

Print setting recommend: I used 0.4mm head, 15% infill, 3 layer wall, 0.3 layer height.
