V3 UPDATE 04-Nov-2023 - Created hygrometer mounting plate for simple set of sensors, removed adafruit sensor thing; updated spindle spinner to include spinning handle for each part; updated spindle holder; added blank spindle plug to fill hole if changing spindle location

V2 UPDATE 27-Dec-2021 - I've added a .STEP file of the MasterAssembly so that any component can be modified or remixed

An assembly of 3D printed fittings that can be installed into a dry-box for filament to spool out of. See assembly drawings and pictures for reference. Recent update included use of two hygrometers (humidity and temperature sensors) for inside and outside conditions. Purchase sensors on amazon here: https://www.amazon.ca/gp/product/B09FZKWHG6

Check out the (old) video of it in action - https://youtu.be/FJr6xU8A37U

What you'll need:

Any size sealing or dry box - mine is about 24in x 16in x 16in tall.
8x M3x12mm Cap Head Screws per spool holder/dowel roller (24 total for mine)
8x M3x12mm Cap Head Screws for hygrometer assembly
1x 17in long pieces of 5/8in dowel per spool holder (3 total for mine)
~5ft x 1/4in PTFE tubing
Drill bits, Dremel, knife for carving out holes
RTV (Room-Temperature Vulcanizing) silicone (if you're crazy like me)
Silica or Other desicant - I used the jar/container from this designer - https://www.thingiverse.com/thing:4821360

Do not print supports for anything EXCEPT PTFETubingPrinterGuideHEX.stl

Please print all parts except those listed below at least .10mm layer height
Please print the SpindleSpinner.STL and PortPlug.STL at 0.15mm
Remove tabs on SpindleSpinner.STL as shown in pictures.

1 Spool Holder requires
2x - DowelHolder.STL
2x - DowelHolderWasher.STL
2x - SpindleSpinner.STL
1x - 17in 5/8 dowel
8x - M3

1 Port Assembly requires
1x - PortBody.STL
1x - PortPlug.STL
1x - PortNut.STL

1 Hosing Assembly requires
1x - HoseAdapterCollet.STL
1x - HoseAdapterNut.STL

1 Hygrometer Assembly requires
1x - HygrometerMount.STL
1x - HygrometerMount_Plate.STL
8x - M3

I applied RTV on all fittings so get a good seal and it worked well. Follow the photos for some help here. It is easy to make a mess - the silicone can be easily peeled away after curing, so if you make a mistake, LEAVE IT... then peel it off the next day. Make sure to apply good sealing around the hygrometer sensors before installing them and after if needed.

To get a good ring for the port plug, apply an amount similar to that shown in the final photos. Make sure you have an even coating and no bubbles, and spin the port plug 1 turn after installing. Always leave RTV silicone at least 24hrs for a full cure. Straggly bits can be easily peeled off.

Make sure the SpindleSpinner has a clear space to freely rotate if you apply silicone to the DowelHolder assembly - scrape cured silicone excess inside the groove before installing.

Plug the PTFE tubing into your current setup/printer, or if you have a Prusa MK3S, the two parts below can be fitted and used as well. See the additional rending for an exploded view.
