Description

I tried many different approaches from building my own (expensive) filament box with aluminum extrusions and sealed acrylic glass to single Rubbermaid boxes with humidity sensor and Silca gel.

This is now the one I settled for and I am quite happy with the cost / performance. It is a modular approach to creating an affordable DryBox that fits four 1kg Prusament Spools but also larger (2+kg) or slimmer (samples, etc…) ones.

Minimum Configuration:

1× IKEA Samla 22L Box with Lid
2× 8mm Threaded Rods (320mm length each)
16× 608ZZ Bearings (ABEC7 or above)
4× E3D Threaded Bowden or 4× PC4-M10 Coupling
4x PTFE Transparent Tube (4/3mm OD/ID)

Assembly Guide:

The labels can be glued permanently or for more flexibility use a magnet (max diameter: 10mm, max thickness: 1.5mm) in the cutout.

You could save on the bearings and just print the circular spool holders but I wanted to have that added smooth rotation. For the filament exits I still had a lot of E3D PTFE Couplings laying around from my previous attempts with the Rubbermaids. But I figured standart and cheaper PC4-M10 couplings also work. For the future I want to design a printable solution that works without purchasing parts but for now that works great.

I also added an AQARA Humidity & Temperature Sensor (Zigbee) with custom slide-in mount. I have this integrated in my home assistant dashboard alongside with Octoprint via MQTT. I find this solution better now then the simpler circular humidity sensors you can also find on various dryboxes. I noticed it seems to be also much more precise.

Printing should be very straight forward. I used PETG. For the Threaded Couplings I would advise a fine resolution or recut afterwards with an BSP G 1/8-28 or M10 thread cutter.

If you would like to have additional airtight sealing use rubber seals on the lid and print the additional pressure fit clips to hold the lid tight. 4 clips should be sufficient.

Silca Gel can be added on fine-meshed bags on the bottom of the box to further reduce humidty. I picked up some from amazon (33 x 25 cm) which fit perfectly.
