DescriptionThis is a miniature magnetic keychain caliper I designed. The caliper is accurate within about .2mm (assuming your printer is calibrated). A lot of care was taken to get all fits clearances and labels right. I would recommend using the Bambu .3mf pre-sliced file included as I modified a number of values to improve final printed results. This was used as a free giveaway for my brand Don't Panic Studio check us out if you are curious Don't Panic Studio ;) ASSEMBLY4x [2mm H x 4mm D] magnets are in the design 2x in the calipers main body and 2x in the slide body. All magnets need to be place in the same orientation! The main body print needs to be paused to embed the magnets. The magnets are optional, but are intended to keep the jaws from falling open when on a keychain. The magnets also help locate the two pieces of the sliding body. Sliding body clamps together without glue, but should be glued with CA if you are carrying it on a keychain. Optional but if you want to
