The file 'Slit For Piggy Bank Socks 3D Printer Model' is (scad,stl) file type, size is 25.9KB.
My mother knits socks as piggy banks, and she ran out of slit inserts.
The slit consists of 2 identical parts. To assemble the slit, the 2 parts need to be pressed together and twisted until the slits are aligned. With the given tolerances, they fit very tightly. No glue or screw is required.
The thing is a customizer, so you may change some dimensions easily. With the default parameters, the slit is big enough for big money ;-)
