Filament spool shaft (hygrometer, desiccant)

thingiverse

I wanted to put a desiccant and hygrometer on the filament, so I tried a few things to put it all together. ・The spool holes need to be 35 mm or more in diameter and 65 mm or less to fit. ・By inserting a short PTFE tube at the bottom of the filament spool shaft, the spool rotates smoothly in a sealed container while staying horizontal. If there's a tangle of filaments, it will get caught. ・Drill a hole in a Japanese pickle sealing container and use a glue gun to secure the PTFE tube as a filament guide. ・Place the filament spool horizontally in the container and feed the filament to the 3D printer. We were able to make a good one by using many designs as references. I would like to take this opportunity to thank you for your help. Thank you very much. I hope that I can be of service to you. The design that we used as reference was from Universal Filament Spool Holder. https://www.thingiverse.com/thing:2070272 Inside Spool Desiccant Holder is another great design we found on Thingiverse. https://www.thingiverse.com/thing:3339561 We also used Cheap and easy filament storage and filament supply box with cap as a reference. https://www.thingiverse.com/thing:3062164 If you can't find the same container, we designed this one with an incline to help with spool rotation. A Japanese pickle sealing container is perfect for this project. You can buy it on Amazon. https://www.amazon.com/Tombo-Container-Sushi-Sealing/dp/B001UJMMZQ/ We also used a digital thermo-hygrometer in our design.
