Fixed blade utility knife handle

NOTE: insert blade before heat set inserts. Otherwise, plastic will melt into where the blade goes, and ruin the part.

A sturdy utility blade holder that fits comfortably in the hand.
Print with spine down (long, narrow, flat edge).
Hardware required:
2x M3x4x5mm heat set inserts
2x m3x8mm cap head screws

printed with supports and skirt, 1.2mm wall thickness horizontal and vertical, 30% infill.
Took about 3.5 hours for me.
