About this 3D model

This metric screw fit/tolerance guide features holes for M2 and M3 screws (2 / 3 mm) with clearance to interference fits, designed to help you find the right dimensions for screw holes in CAD. This model is available as: M3 - M6 (original) M2 - M6 (this model) M2 & M3 (Remix) Finding the right hole size for a screw is difficult without testing first - in the best case you're looking for self-tapping holes with a fit tight enough so that the screw can live up to its highest potential, but without significant warping to the 3D-printed material. With this guide it's made easy for a variety of screws you might have on hand.
