A 2x1 Gridfinity holder for the first generation Rapsberry Pi Model B from 2012.

If you are like me and have a stack of old PIs lying around that you occassionally use for random hacks, now you can keep them nice and organized in your Gridfinity.

Tested with a X1C using Bambulab PLA in beige. The fit is neither too tight nor too loose.

5% infill works fine if you want to save material.
