Do you need a way to easily rewind excess filament when using a dry box? Read on for an add-on to use with these (or any similar) dry boxes. I have made a dozen of these dry boxes, they work fairly well other than sometimes I have issues with the end of the spool not having enough weight to keep it on the axles, and the spool doesn't always engage with and rotate the axles; and I did use TPU axle hubs. I also de-greased the bearings and then applied oil to them for smoother rolling. For the most part, these do what I need. I like how the top mount hygrometer piece gently rides on the spool, assisting with retaining the filament on the spool if/when filament back feeds.
Here is my solution for rewinding the 2-3 feet of filament that is left out after unloading from the manual feed port on my P1s. This is made a filament spool desiccant holder with 1/4" square drive hole, and a port with plug for the side of the cereal box to access insert a 1/4" bit driver to wind the filament back in. I've now included a printable 1/4" drive tool. The spool core was inspired by Willi 3D SpoolCore, so credit to Willi 3D on the core-concept.

I've also made a different filament cap for this or any other drybox using pneumatic fittings to address 3 issues I had- The cap included with this tends to snap off easily, it does not prevent the filament from falling back into the drybox, and I found it made it difficult to release the fitting if the cap were pushed all the way in. This new cap uses a small piece of PTFE, and has internal nubs to hold the filament in it, preventing the filament from falling back into the drybox. Here a link to the cap: https://www.printables.com/model/1169077-filament-cap-for-drybox-with-pneumatic-fitting
Hopefully my review of this nice dry box and contribution of a rewinder is useful. (edited)
