I tried the other cable holders but my cables would fall out. I thought I'd give a remix a try
with a Spring loaded lid on top to hold them in. Double stick tape will hold them down but if
you don't want to use tape I provide one with a remixed clap design. Command strips work
great to hold them down and you can even mount them from underneath( i.e. Tape top On
top. Hope they work as well for you as they do for me enjoy. With and without bunny ears
because everything's better with bunny ears.
3 Outlines/Perimeters. If you use S3D make sure you turn on "allow single extrusion walls" and "allow Single extrusion fill".
I have only printed them in PETG but I think almost any filament will work.
