Sometimes you need to run a cable in a clean manner and also be able to remove it quickly and take it with you.
I printed mine in PLA and they are very strong. PETG is probably even better.
The screw driver access hole allows for it to be much more compact
I made two versions, one is for flat head screws and the other is for round head screws.
Both were designed with #8 wood screws in mind.
If you plan to use flat head screws, don't overtorque, this could split the layers…
Nothing too special but certainly handy…
Enjoy!
