Dụng Cụ Cắt Giấy Carton Thành Sợi

This is another variation of the cardboard strip cutter. In this one I take advantage of the comments made on other versions of this tool to come up with my own take including the additional length. It cuts 40mm strips, which was the same as the cat scratcher I had at home.

This is designed to accept a utility blade common to the North American market (see attached dimensioned drawing). The retaining nut is M3 sized and is not intended to provide any clamping force, but simply to keep the blade from backing out of the pocket.

The angled design is intentional in order to make sure the layers have as much contact as possible. The angles also give you options for hand holds. I've also rounded the edges to make it comfortable in the had.

Printing Tips

1. Slice your own for best results.
2. No supports required, but I recommend using brim.
3. I printed with a .4mm nozzle, .2mm layer height, 3 perimeters, and 20% infill.
4. If you're left handed, mirror the object in your slicer.
