I wanted to rise my pc from the floor so the robot vacuum cleaner could get under it. I have searched for some alternatives, but did not find any so I have created my own.

I have made it for my own case Asus tuf gaming gt302 but I think you can adapt it to other cases. 

The corners are not symmetrical. One length is 117,50 mm the other one is 121,00 mm.

You will need to print 4x legs and 2x corners 2x mirrored corners. I printed with PETG 3 walls 10% adaptive cubic infill 

In my case I used d16 pvc pipe:

4x 156 mm

4x 405 mm

16x 140 mm

I hope this will be useful for someone.
