IKEA SKADIS Shelf for IKEA GLIS Boxes

I needed a shelf for our son's IKEA Skadis system that keeps his GLIS Boxes nicely organized.
Because I couldn't find any finished designs, I quickly created this one myself.

The shelfs are of course not only working with GLIS, you can also just print and use them for any other things you want dump on your Skadis wall. 
The inner diameters are 150x93mm

I printed it in PLA but PETG would probably be a better choice here.
Use Support to make sure you're not printing those little hooks in mid air.
