Cat Scratcher Cardboard Strip Cutter No Supports No Heat Set Insert

by Iangenuity

This device is designed to print without supports and be used to cut cardboard strips to make a device for cats to claw at and scratch. This devices requires a standard utility blade and works well with an M3*10, M3*12, or M3*14 screw. An M4*8 screw is optional. The M3 screw can be installed from either side depending on user preference.   I loved the original model but I didn't have any heat-set-inserts, so I chose to reduce the size of the hole so that the M4 could tap itself into the plastic. While in there I also added an M3 bolt hole so that I could put a bolt through the slot in the utility blade and truly lock the blade in place. The M3 also taps itself into the plastic and does so securely.
