PiHoles is an OpenSCAD library which provides mounting hole positions and board dimensions for designing Raspberry Pi accessories. I wrote this while designing a Pi mount for my 3D printer for use with OctoPrint, but hopefully you'll find it useful as well.Currently, PiHoles provides the ability to create mounting holes for Raspberry Pi boards with a preview of where the board would be. In the future I hope to add support for the Pi's various ports.Supported Raspberry Pi versionsPiHoles currently supports Raspberry Pi 1B, 1A+, 1B+, 2B, 3B, and Zero. The dimensions used in PiHoles are sourced from the Raspberry Pi Foundation's offical documentation (https://www.raspberrypi.org/documentation/hardware/raspberrypi/mechanical/) where possible, and based on my own measurements in the case of the 1B.For full documentation, see https://github.com/daprice/PiHole
