Summary

After printing the parts from Biolook, I was afraid that the screws were too close from the edge of the part. So I decided to remix it and bring the screws inside the part.
I removed the cable holders because we don't use them, our desk is too messy anyway and they protrude.

Other dimensions are more or less the same.

We used a 1mm nozzle to print it quickly so the result is not very fine nor pretty but the functionality are ok.
Moreover we had an issue with the filament running short with no detection on our Ender 3. The time we succeed to replace the filament a few gap were created here and there. I used a 3D pen to fix the part and fill the gap (and add some colors into the letters). That's why there is so many colors on the picture.
