GUN - Gravity Utility Knife V1.1
Have us print this for you
PLA from £6 inc. UK delivery on letter-sized prints. We slice, print on a calibrated Creality K2 / Bambu A1, QC and post.
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.
