Dry Box for Prusament

This is a dry box I designed specifically for prusament. It is based on a Rubbermaid 21-cup dry food storage container. It has a bowden bulkhead fitting so you can add bowden tube to print directly from the box and you can plug the coupling when not using it.

I used hot glue but you could use silicone RTV to seal the holes when putting the screws in.

Do your best to make sure each side roller is lined up properly.

the bearings are press-on but when printing on my Ender 3, I noticed that the studs that hold the bearings weren't sized quite how the dimensions of them should have been. So I have added a second version that has slightly larger studs to press the bearing on to.


In order to build this you will need:

1x Rubbermaid 21-cup container
1x Printed Roller
1x Printed Hygrometer mount
2x printed Bearing Roller
1x Bowden bulkhead fitting (https://www.amazon.com/gp/product/B07MLJYQYR)
1x Round hygrometer (cheap and plentiful, search Amazon for best deal)
