Tiny pocket EDC 4mm hex bit screwdriver keychain

Welcome back witches and wizards! This time not very magical, but practical! I designed 3 versions of a tiny keychain 4mm hexbit screwdriver. Big version holding 6 bits with a stable outer thread Thinner version holding 6 bits with an inner thread Really thin version holding 3 bits with stable outer thread I designed holes for 3x1mm magnets to push into the bit holders. They snap fit and hold the bits pretty well. Attaching the magnets: Just but one 3x1mm magnet on the end of a bit, and then push the pit pretty hard into a hole untill you hear a satisfying “click”. I push the screwdriver with the bit downwards on a scratch resistant table surface. Printing is easy: put the main body always on the top end with a brim, so the threads print perfectly: put the lids on their flat side activate arachne wall mode! otherwise the walls between the bit holders wont be printed properly I suggest 0.12mm for high details the shown models are printed in silver PETG
