This is a hardware free and support free handle for standard utility blades. It works good for part removal or other tasks around the house.

I put a pause right before it started to print the top of the blade slot and inserted a blade instead of using support since it is such a small gap. This gave it the perfect amount of friction to hold the blade but still be removable by hand.
