Hobby knife with a finger loop for more precise and delicate tasks. It was inspired by one I saw on Amazon but designed it from scratch/remixed it from the Inexacto Hobby Knife.
Print the modified sleeve if the blade is too loose. It's been lengthened to catch the blade edges and provide more stability.
Disclaimer: Obviously hobby blades are sharp, be careful!
Please post your prints! I'd love to see them!
4/9/2021: Added a modified sleeve for any slippery blades. Successfully test printed the 4-way holder
Printer brand: Creality
Printer: Ender 3
Infill: 20% and 100% (Knife holder part)
Filament brand: Hatchbox
Filament color: Orange
Filament material: PLA
Notes: I used a brim, 3-4 shells, 20% infill (100% for the knife holder part)
Note: For the knife holder part it's probably best to use 4 shells and bump up the infill (possibly best to 100%). Especially if you want to tighten it down a lot.
Hobby_Knife_Holder.stl and Hobby_Knife_Sleeve.stl are from the original Inexacto hobby knife
I didn't have difficulty with mine but one of the makes mentioned difficulty getting the threads to work until printing it in this orientation.
