Drill guide for business card. For hanging earrings or other bits of jewellery. Useful if selling jewellery at market stalls or shops.
Fits business card size 91mm x 55mm, but can be used for similar size cards as you can just lay the frame on top of the card and line it up so all exposed edges are equal. This one is printed in PETG but PLA would also work fine. Holes are 2mm diameter so use a 1mm or 1.5mm drill bit.
