Filament switch

I'm a complete noob using Fusion 360 and an inexperience maker, so don't judge me too harshly. This is a project to bring some order to my filament stored in a cabinet and to make easy filament switching easier.
The project has some flaws and would benefit from some adjustments by more experienced makers. I printed it using ABS and it may have been shrinking or just poor understanding of how printing actually works, but I had to drill the holes for the tubes to make them fit and avoid squeezing them. It still feels like the tubes are a bit squeezed, using a 4 mm drill both for the switch and for the cabinet holes. It is however, probably good enough for my use and I'll leave it there. Of course, any improvements to the model would be greatly appreciated! The Fusion 360 file is included.
