Wall spool holder and bobbin holder

My girlfriend really likes sewing. The pain in the butt is that she had a lot of spools with all colors of thread (I can name only like 5 of them) and they were everywhere. Then I have put my tools up on the wall behind the work table, and she wanted something like it too. So I have designed her spool and bobbin holders.

There are 3 separate models. The has 4x4 "horns" for the spools (printed in white PLA), the has -you have guested it- 5x5 "horns". The bobbin holder has a fixed number of bobbins, as they are pretty standardized. The bobbin holder is a bit parametric, but it was my first parametric model, so I think it will break after a few minutes of tinkering with the parameters.

All of the models have screw holes because pegboard is expensive as .... in my country. On the picture, it looks like a pegboard but definitely is not, because the holes are not in regular distances. But I guess if you use pegboard, it can be remixed very easily.

May your threads never get tangled.
