Another Filament Dry Box (with printable PDF drill guides)

About the model

A basic filament box capable of holding 4 spools of filament. These files provide the basics to build the spool holder and a few extras. The rest you can really build how ever you like. If you want to build it exactly as I have, you will need the materials below. VERSION 2: Changes: • Made the design a little simpler to use • Spool rod is not locked into place. Just slides in and out for easier removal, but will still be retained in place • Slightly modified Feeding and Return nuts • I am working on a system to eliminate tangles and filament jumping over spool walls. If I finish it, this will be the version it will be based on • All print guides and hardware stay the same in version 2 Features: • Hygrometer for temperature and humidity levels • Individual bowden tubes for each roll • Choose to feed the filament out the top or bottom • Gasket sealed box • Printable PDF drill guides so there is no guessing Files: • Complete Part File - all the parts needed in the correct orientation as I have built this box • Spool_Hygrometer - one side of the spool holder with included hygrometer mount. If you don't want the hygrometer print two of the “Spool” files • Spool - one side of the spool holder • Feeding Nut - this has a smaller hole to allow feeding of the filament from the inside of the box. Goes on the back of the bowden tube pneumatic fittings. • Return Nut - this nut has a larger hole in the back to allow storage of the loose end of the bowden tube when not in use. Goes on the back of the bowden tube pneumatic fittings. • Plug - used to keep air out of the box when one of the spools is in use. Just plug it into the pneumatic fitting from the outside. • Baffles - a file made by nscale to help prevent tangles can be found here • Desiccant Box - a desiccant box designed specifically for this dry box. Two of them should fit nicely under the spools. Parametric version can be found here Required Materials: • 8 M3x10 screws and nuts - https://amzn.to/3FP6AHA • About 12.5 inches of ¾ inch PVC • 8 bowden tube pneumatic fittings - https://amzn.to/43R9Rht • 2 ft of 2mm ID bowden tubing - https://amzn.to/45OYr0k • Hygrometer - https://amzn.to/4kTTTdo • Desiccant Pack - https://amzn.to/43Rjvkg • Storage Tote - Sterilite 20qt gasket tub - https://www.walmart.com/ip/Sterilite-20-Quart-Gasket-Box-Weather-Resistant-Clear-Storage-Bin-with-Lid-Blue/39916455?classType=VARIANT&athbdg=L1103&from=/search Few notes on the supply list; These are affiliate links to the exact materials I bought and they all seem to be good purchases so far. The desiccant pack is probably a little over kill but works very well. I bought two, you really only need one. Also, this project is designed around the Sterilite tub linked above. I think amazon has it but it is only $7 at Walmart. Print Settings: Nothing real complex here. I printed at 15% infill with basic settings. I might increase the infill for the base around the 'C' shaped parts and I would maybe do 100% infill on the plug and nuts. Everything else is as normal.
