Razor Blade / Utilty Knife with heat-set insert

I redesigned the knife so that a Voron-sized M3 heat-set insert fits correctly ( diameter: 5 mm, length: 4 mm ). The hole diameter in the CAD model is 4.7 mm. The new design is extremely rigid, and the blade can be replaced as often as needed without degrading the structure. BOM (list of materials): - 4× M3 heat-set inserts (diameter: 5 mm , length: 4 mm ) - 2× M3 SHCS screws, length: 12 mm - 2× M3 SHCS screws, length: 4 mm - (optional: M3 washers) Assembly: If the blade does not slide in smoothly but is correctly aligned (see last picture), loosely fasten the front screw. Place a piece of wood or PLA on top of the blade and gently tap it into position with a hammer. Always keep the wood/PLA piece between the hammer and the blade to avoid dulling the blade.
