Here is a small and easy to print test lead hanger.
It measures 50X20X20.
The area for the test leads to hang from is 10mm’s wide.
I stuck this to the side of my tool box with some very high bond double sided tape.
It’s a very easy print. No overhangs.
I printed this in ABS, .2 layer, 50% infill, but I’m sure it will print just fine in PLA also.
