2020 Cable Clip

Holds a cable in some extrusion! Has a taper to make it easier to slot in.  There's a good chance you'll want to modify the dimensions to make it work with your particular 2020 and your printer's tolerances. Sorry, I didn't do a good job of making it parametric.

For inside of an enclosed printer, be sure to use something that won't creep, or your cables will start falling out.
