Cereal Container Filament Dry Box Lid (PARALLEL TUSH)

I tried many different variations of a dry box spooler system. All the ones with printed rollers caused the spool not to roll correctly. The ones with metal shafts caused the spool to become misaligned and not stay centered. Every design I tested would eventually touch the container wall and jam.

I have always had success using the TUSH spool holder and never encountered issues. However, the one drawback of the TUSH spool holder is keeping it centered in the dry box—it tends to rub against the container wall.

This remix combines the "TUSH PARALLEL" upgrade with an additional linkage to keep the spool centered in the box. It also incorporates the original lid design from the "Filament Dry Box with Rollers," where the lid base fits inside the lid. The added bottom base replaces the cap and includes a filament path guide that uses a PTFE tube. This allows the filament to exit the container without the need to drill holes. The space between the lid base and the cap base is used to store desiccant, which is filled from the sides and sealed with the provided side covers.

All parts are printed flat with no supports.  The Sled and Hydrometer is mounted to the top base with woodscrews.
