Razor Knife

thingiverse

I'm helping set up a Maker Space. You shouldn't have to buy tools when you can make many common ones using your new digital fabrication tools. I'm actively involved in my local makerspace (www.makerspace307.org) and know how quickly costs can add up when outfitting your space. This is an easy, inexpensive knife you can make using a 3D printer. The total cost is under $0.50 using filament that costs around $22.00/KG and Stanley classic utility blades (No. 1992). I've designed the file for printing in PLA. If you print this in another material or use a different brand of blade, please let me know how it worked. Special note: The blade cover is designed for printing with a 0.40mm nozzle/extrusion width, if you have a different width you may experience difficulty. THINGS TO DO: Upload blade cover Done! Create hole for hanging or lanyard Create collection for makerspace tools Add spare blade storage if possible Instructions -Print either version of the knife body in the orientation as shown in the preview (55 degree Y rotation). I've already taken care of this in the "Oriented_Razor_Knife.stl" file. Supports are only needed from the buildplate in this orientation. Just make sure no supports are printed inside the blade pocket. I print my knives at 0.3 mm layer height -Print several of the pins, pick the best looking one and make sure they're oriented vertically -Slide a blade into the slot in the end of the body then insert the pin through the pinhole, securing the blade. When the blade is dull remove the pin and replace the blade
