Compact Utility Knife

3D model description


The goal of this project was to make a simple and clean utility blade holder. This utility blade holder is quick printing (20 minutes), lightweight, and strong. When no other option is available, this should work in a pinch. Version 2 blade will fit tightly.

The ability to use nuts and bolts is optional. Provided you allow the blade to be a permanent part of the knife, you can use ABS slurry to glue in the pins.

Version 1 is pictured. Please note different handle cutout.

Version 2 holds the blade slightly on bottom to prevent falling out.

3D printing settings

Print body with butt of knife on platform. 10% fill, 2 shells should be fine. Print filled for a stronger knife body. Finish by attaching pins to body, and gluing with ABS slurry. Alternatively, use M3 nuts and bolts.
