Cable holder

I did these two different sizes cable holders to hold power cables and internet cables under my desk.

The smaller one measures 20mm x 15mm on the inside and the larger one measures 20mm x 24mm on the inside. Both have a 3mm thick wall and 12mm of height. Attachment using double-sided tape.

Please feel free to make any changes, I just ask you to notify me so I can also check it out.
