Skadis Paint Holder - Pro Acryl (30ml) - Stackable

I honestly have no idea what I'm doing with 3D Modeling, but I found the basis for this model from InTheRedShirt on Thingiverse - I wanted a cutout in the front to be able to see the name of the paints, so I kind of fooled around with Blender until I managed to get something that works. The dimensions and measurements aren't perfect across all the holders, but it's close enough that I'll never notice the difference, so I figured maybe someone else can appreciate this.

I also noticed that none of the other Pro Acryl holders on MakerWorld are able to properly stack side to side and vertically, so this was another huge benefit of this specific one. It being a single piece is icing on the cake, no glue! From what I can see, the universal hook design for the Skadis is by CSD_Salzburg, so big thanks to them for that. I just sit the holders on the hooks inside the Skadis. Stacking from the bottom left to the bottom right, then up a row and repeating is the easiest way.
