This Raspberry Pi case is designed to fit into a standard 3.5in hard drive slot. It works well with tool less mounting systems, but I also added the ability for threaded nuts to be dropped in which work great as well and make this compatible with anything that a standard hard drive fit into.
The nuts that I built around are the McMaster-Carr 90480a007 This cost me $8.32 for 100 nuts delivered to my door but I am sure a local hardware store would have the same thing far cheaper.

Notes:

I have printed this part a few times and you can get away with doing no supports you just end up with some long bridges. I would advise against supports inside where the nuts go because it is nearly impossible to get those supports out correctly.

How I Designed This

This was my first project using Fusion 360, and my first project built from the ground up for 3D printing. I started by building a profile sketch or “master sketch” of an HDD with the placement of the screw holes. Then I decided to make a rough Raspberry Pi model since I plan on many 3D printed projects for the Pi it would be easier to have a digital copy.

Version 2 will be worked on soon since now I have experience with 3D printing and I know that things like the long supports that require long bridges are a big no no. Ill also probable change the positioning of the Pi to be more in the middle. Any other feedback would be greatly appreciated.
