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.

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.
