Give your empty Prusa spools a second life with this modular storage solution! This 3D printable insert transforms a standard empty Prusa filament spool into a compact, stackable organizer with six individual compartments—perfect for storing small parts, hardware, or hobby supplies.

Whether you're organizing screws, LEGO pieces, or electronic components, this spool-based storage system is a smart and space-saving solution for any maker's workspace.

One spool:

For assembly: 
1. pull the spool apart and insert the bolts. There 6 spots on the spool were the bolts fit.

2. Put the spring into the stand and slide the Spool-adapter onto the stand. 
3. Put all the drawers on the bolts and press the spool together
4. slide the spool on the stand

If you want to use the double version just repeat the process and use the “Connector” instead of the “Stand” (don't forget the spring) and put the two spools together

You might need to scale the lable a bit down. I would recommend only to print one lable first and test it.
To remove the lable just use a screwdriver and insert it in the gap on the bottom left.

For the stand, please use some rubber feet that the spinning mechanism works
I use these ones:  https://www.amazon.de/dp/B09TW15NHP?
