These are parts that you can use to convert a Prusament spool cardboard core into a container.
Insert the top and bottom parts from both sides into a spool core. The "teeth" on the parts align with the teeth on the original spool sides. First, try to align the printed parts with the grooves that were left after spool parts. If there is not enough friction to hold the part in place — insert it in a way where the teeth don't align with the grooves.

The first version that I made was a remix of the CONTAINERS - PRUSAMENT SPOOL - reuse idea by Dominik Císař. I didn't like how the first version performed so I redesigned the project from scratch.
0.2 layer height will work, but smaller layer heights result in better screwing experience.
The author marked this model as their own original creation.
