RPG Grifinity Baseplate

This is a baseplate for an RPG type gridfinity but it uses a 25mmx25mm size and the squares will lock in I will upload some time and the freecad file allows for any size just edit the spreadsheet, this is still a work in progress UPDATE: Uploaded a baseplate v2 with a slightly better bottom chamfer (the old one will warp a bit with a lot of tiles in it)
