About this 3D model

I’m new to the world of 3D printing and got a Thing-O-Matic for my upcoming 50 birthday. I have seen several other filament holders but wanted to make my own, and here it is. I’m not into volume production so I don’t need an automated feed system. As the printer will be stored when not in use it had to be simple and I don’t mind pulling out the filament needed manually.
