Use this compact cutter to cut sealing tapes, open bags, or cut shrink wrap. It uses common #11 X-acto blades, so you can always get a new sharp blade. The blade tip is always covered, and the gap is very narrow, so it can be safely carried in your pocket.

The blade slides into the groove at the back and then into a pocket. Then, you can use a 7mm-long 1.75mm filament

Print according to the provided orientation without the need for support. Use a 0.4mm

Note: This version is a major revision of the version I originally released, which improves the attacking angle of the blade.
