Meanwhile, my anycubic 3D printer printer is slowly getting hot and is almost permanently in use. The required filament is then consumed in the appropriate quantities. This raises the problem, what to do with the empty filament spools, throwing away would be too bad!
Surely there must exist a good and meaningful application. After doing some research, I found a solution. On thingiverse a design is available with which one can use the open-source software openscad to print a slot adapted to the respective coil dimension, which can then be used as a small parts box or similar. I’ve modified this design to my needs and also released it on thingiverse as a remix: https://www.thingiverse.com/thing:3198728
Thus, it is now possible to use the empty filament spools as a collection container for small parts. In addition, the so converted coils can then be stacked on top of each other and serve as a space-saving small parts magazine. Have converted to an old IKEA table leg made of metal, because the coils could be pushed with the inner diameter just above it and stacked so. The following photos show my solution:
