This is a compact and easy-to-print foldable art knife, which can be used with standard art knife blades. The design takes full account of the convenience of printing, and it can be formed in one go in a flat way without the need for a supporting structure. After printing, you just need to glue and fix the blade assembly with adhesive, and then assemble it with 2 M2 12mm screws and nuts.

By properly tightening the screws, you can effectively prevent the blade from slipping and allow the blade to be easily opened and closed with one hand after a slight break-in period. You may need to fine-tune the tightness of the front screws according to your personal usage habits to find the most comfortable grip and operating feel.
