This is a remix of the cable management model by Aelphy, designed to fit a 22.1mm desk plate, which is the standard height of some IKEA desk plates.
I added some small nobs, so that the power supply underneath stays in.
You can adjust the tinker cadmodel to your needs if you need another desk height.
I printed it in standard PLA, 10% infill and no supports on my Creality Ender 3v2, and it works fine. The little nobs that are supposed to hold the power strip where not super clean, but they are not visible normally anyway and still hold the power strip.
The author remixed this model.
