This is a simple radius Gauge design to help measure radii from 1mm-20mm. It can be used to visualise the size of a part that you are designing on CAD, or to directly place on objects to work out their radius. The design prints in two files and is three kit cards put together, the pieces are printed in one and the other file is for the two cases/holders. Total print time is around 3 hours with no AMS or colour changing required. Once printed the cases/holders can be easily separated from each other with a small amount of force. The radius gauge pieces come apart just as easily, but may require a quick once over with scissors or a blade to remove the connection tabs in order to properly fit into the case. All radius gauge parts are labelled in mm from R1-R20.
