This is a mount for a Raspberry PI 3/3+ to use on a desktop or flat surface and present the top of the rasPI at a 60 degree angle from horizontal. You should also be able to use it with RasPi cases that expose the mounting holes in the same place as the motherboard.
There are two flavors, the high profile and low profile. The low profile is good for most cases, but the high profile is good if you need a little more space between the motherboard and the desktop it is sitting on.
It is designed for M2.5 bolts, roughly 20-25 mm, in length, depending on if you are also mounting on a case. The bolts are a little on the snug side in the initial v1 revision, but they do fit through.
I designed this to mount a "pi1541", a Raspberry Pi-based Commodore floppy drive emulator after not being able to find a design for a mount design that held the Pi at an angle. See about the pi 1541 project here
I am fine with people printing and selling prints of this, so long as you attribute me, and also provide a link to this or offer the files for free. I am not ok with selling the model files themselves or selling derivative models. (contact me, if you are really interested in that)
The piece was designed to not need supports, though depending on your print settings and materials, the top of the arch on the mount might be a little tricky.
