My print of this remix include an created .STL for stacking an RaspberyPi acrylic case for home automation OpenHab on top of it. If some body ask I'll make the research for this RaspberyPi case I've purchased years ago (RaspberyPi 2b)
If you take the Fusion .F3D file you will be able to modify parametric values (cntrl+p window user's) and adjust for your needs.
Supports are only needed (and only desirable) for the feet of the various parts.
