Magnetic cable clips - updated

Update April 2025:
Now with three versions, for cables up to 4 mm, 5 mm and 6 mm in diameter

On my Original Prusa Enclosure is mounted a Raspberry Pi with a touchscreen and also a filament dryer stands on top of the box.
Both devices have a power supply, and the two cables run from the power outlet along the case frame up to the top.
To keep the cables neatly routed, I use these little clips made of PLA, each containing two 5x3mm magnets.

The holes for the magnets have nearly the same diameter as the magnets, the magnets fit very tight, they have to be pressed in. This allowed me to assemble them without glue. I used pliers to press in the magnets.
