Description

PDF

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.

Model origin

The author remixed this model.

Differences of the remix compared to the original

Reduced hole size so that M4 self-taps instead of using a heat set insert. 

Also added an M3 hole to go in the slot in the utility blade to prevent it from backing out.
