Designed handles for my Needle Files. Wanted to do this for years now and with the 3D printer it was quick and easy. Uploaded the .STL file so you can modify it if needed.
I decided to use hardware because I didn'Ât want the file to loosen or rotate in handle. Can get the hardware at any home improvement store.
Note: because the "nut pockets" are against the build table you will get a few plastic buggers in the pockets. Use a pair of needle nose pliers to remove before assy.
