Drybox For Prusa XL / 3030 Extrusion

I've designed this drybox for the Prusa XL, of course it can be attached anywhere on 3030 aluminum extrusions.

The drybox is opened via the red wheel with a 90° turn. It also holds the container for the desiccant, which could not be easier to reach thanks to its attachment to the wheel. The lid is also the spring that keeps the lid under tension.
The box has a window to be able to see how much filament is left on the spool. There is also a version of the box that can hold a hygrometer, useful if you are using a desiccant without color indicator.

The drybox is designed so that it can be printed without supports. This also applies to the window and hygrometer cut-out as the bridges are straight. If you are unsure, you can of course use supports.

If you are using the enclosure for the XL, you will find spacers in the Remixes tab which create a distance between the drybox and the handles of the bellow.

By scaling the seal of the lid in Z, you can give the lid more or less tension. The standard thickness of the seal is 3 mm.
The seal of the wheel is trapezoidal. Print it as the file is aligned. The side that is on the bed is the top.

For the window you need a 55x50mm piece of clear plastic, which you can simply cut out of a package and attach to the box with the frame.

There are several holes on the back around the screw into which two pins are inserted to prevent the box from turning.
Due to the small diameter of the pins, you may have to reduce the flow rate slightly so that they are not too tight.

Note:
The container is not 100% airtight, but sufficient for the desiccant to keep the moisture out of the filament.
Of course, loading the filament is a bit more fiddly. I pull out the PTFE tube at the filament sensor and push it at this position up to the extruder.
