This is my take on a 3D printable Exacto Knife!
There are various models on Printables which contain different combinations of features I was looking for in this tool, but none of them got it perfect, so I made my own!
The cap attaches to a key-ring, and the handle threads in. You can remove the handle from the cap without removing it from your keys!
Print Details:
The knurling is pretty grippy- moreso with PLA than PETG (the only two filaments I own at the moment)-
- If you might leave it in a hot car, go for PETG
- If you'll only use it indoors and would like a more grippy handle, go for PLA
I would use a relatively fine line height.
.2mm would cause the threads to separate
.12mm worked perfectly
This prints without supports!
You will have to “massage” (forcefully) the threads for a few cycles before they will spin easily. After that it will be smooth and secure.
The blade will friction fit into a hole in the handle. I recommend using pliers or some other form of gripping tool to do this. Be careful applying force when installing the blade!
The blade will hold very snug once installed correctly.
Due to the structure of the inside of the cap, this will only properly work with the standard precision blade. Extending the cap height by a few millimeters, or removing the inner chamfer and using supports should allow all blade types.
Personal Spiel:
This is my first published 3d model, but I plan for this knife to be a sort of “kick practiced 1000 times”. Please comment any makes and suggestions!
