I remixed the dust cover from Original prusa MINI lbase legs to create a holder for my light cable. The cable I had is standard 2wire 220V, so it will accomodate other cables too.

If you need a different size of cable tunel, let me know and I can remix it.

Printing

I print it standing for maximum strength, with brim, just in case.

The model is 150mm high and after 100mm, it started wobling, resulting in not so nice end result. But I decided it will work OK. If you want to be sure, you can cut the height to smaller pieces and use multiple.
