square filament dry box

Square filament dry box

- Small body for compact size. Big body for more space for desiccant.
- Thin lid for simple look. Thick lid for better seal.
- Lid with window to show filament color and desiccant status. Optional no window lid for easier build.

other required hardware:
- 608 bearings x 4 ( for the roller )
- M3 screws x 12 ( I use M3 x 10mm, but other length is acceptable )
- M3 threaded inserts x 12 ( mine are 5mm in diameter and 8mm in height, but there are so many different shapes and sizes out there. )
- one PC4-01 fitting for the PTFE tube to pass through.
- 1mm acrylic sheet is glued to the lid as the window.
- 0.5mm / 1mm thick EVA foam tape can be added to the lid for better seal.


Most models do NOT need support. Small amount of support is needed for the countersink of the screw holes of the left and right roller holders.
