GUN - Gravity Utility Knife V1.1
Description
Inspired by the Reate Exo-U i did my own attempt on a grivity knife. This might be work in progress, so possible that there will be further versions. My original Design is for use with M2x2 heat inserts, but i also added a version for M2 nuts (untested) Prints without any support. For the stopper of the bladeholder its possible to use a M2x4 heat insert instead of 2x M2x2. All holes facing the buildplate but don`t touch it having a 0.2mm layer to bridge the hole before printing on it. These has to be drilled/cut out afterwards. Handle parts printing upright. Inner handle facing bottom to buildplate, outer handle facing top to buildplate. Recommended to print with strong material. Printed mine with PETG-CF. Use at your own risk! I'm not responsible if you hurt yourself with this. STEP included, feel free to remix. Update 1: Added the file "GUN-PrintOrientation.3mf" where i placed all objects like i printed them without support. Update V1.1: Added some BladeCover and also a BladeHolder with a longer cutting edge. BOM: - Heat Insert Version - 6x M2x2(L)x3(OD) or 4x M2(L)x2(OD) + 1x M2x4(L)x4(OD) Heat Inserts like this one: https://de.aliexpress.com/item/1005006071488810.html 1x M2x14 Screw 3x M2x5 or M2x4 Screw 2x M2x3 Cylinder Head Screw - Nut Version - 5x M2 Nut 1x M2x14 Screw 1x M2x12 Screw 1x M2x5 or M2x4 Screw 2x M2x3 Cylinder Head Screw
