UPC Barcode Generator

thingiverse

This is a module that generates physical barcode objects with the given barcode number. It can be made into keyrings or printed on other 3D objects. The creator's primary purpose is to print grocery store VIP cards with anonymized numbers, aiming for mass adoption among friends to pollute customer databases. Barcode printing requires a dark color and light background; for darker complexions, the argument can be inverted for white or red plastic. A sample program demonstrates usage with arguments for barcode number, height, stretch width multiplier, keychain shape, inverse lines/spaces, and laser cutter export. The module seeks help to collect 12-digit grocery store VIP card numbers, requesting only the first six digits (starting with 4) for anonymized generation. A list of collected barcode numbers is provided, encouraging users to print on paper if they don't have a printer.
