Universal Filament Storage / Spool Rack v2

Designing these models is HARD, and sharing them makes it harder. Creating these designs takes substantial time and effort, involving a lot of testing and a significant amount of filament wasted until the perfect design is achieved. While making models for my own use is easier, sharing them with others requires additional work. The designs need to be more foolproof and universal, and I have to create all the profiles, take pictures, and write descriptions and instructions. Your support would be greatly appreciated. Boosting my models would really help me continue sharing these designs with you. Thank you!
