This is my go at an Ender-5/Ender-5 Pro Bed Cable Strain Relief.
I printed this in PET-G with 85% infill, and supports but with support blocker at the holes.
This is a model with idea and dimensions based off of:

but this is not really a remix. I made the model from scratch in Blender,
following it's general shape as it fits on the printer.
I did end up making the shape very similar. So I hope that does not violate anything?
