Silica Gel Container for (almost) every spool

Welcome, friend of dry filament! I designed a bunch of Silica containers and hope that they'll fit your needs. They have different dimensions to fit in your filament spool, feel free to message me if any combinations are missing. How to select your parts : - What are the inner diameter / bore and width of your spool? (in millimeters, it'll be easier to put parts in tne spool if you pick yourDiameter = spoolDiameter - 1 mm)

- Do you want to use a hygrometer? - Cap: print cap_hygrometer_"yourDiameter" - Your height for the bin: Your spool height - 24 mm (because the hygrometer has 24 mm height) - Bin: print bin_"yourDiameter"x"yourHeight"_hygrometer - Optional: print a filter_??? part to prevent gel from getting inside your hygrometer. 5mm will fit if there is no gap in the cap, you might want to print a different height if your hygrometer has a recess. (I tried to make a picture of what I mean, I hope it helps) If you pick 5 mm + yourHygrometerRecess, you should be fine.

- Without hygrometer:- Cap: print cap_holes_"yourDiameter" - Your height for the bin: Your spool height - 12 mm (because the perforated cap has 12 mm height) - Bin: print bin_"yourDiameter"x"yourHeight"

Examples: Spectrum Filament has 67 mm width and 52 mm inner diameter > for hygrometer cap_hygro_51 + bin_51x43 (67 - 24)_hygro; for no hygrometer cap_holes_51 + bin_51x55 (67 - 12) Bambu has 67 mm width and 55 mm inner diameter > for hygrometer cap_hygro_54 + bin_54x43 (67 - 24)_hygro; for no hygrometer cap_holes_54 + bin_54x55 (67 - 12) Sunlu v3 has 68 mm width and 55 inner diameter > for hygrometer cap_hygro_54 + bin_54x44 (68 - 24)_hygro; for no hygrometer cap_holes_54 + bin_54x56 (68 - 12) If you're unsure if the combination will fit, just take the next smallest combination. Printing times and filament consumptions for 0.2 mm layer height: (20 % infill and 30 mm/s print speed, using brim was helpful for me) - Bin: varies from 3h 4m and 15g for variant_48x31 up to 5h 31m and 26g for variant_56x56 - Cap_holes. goes from 1h 45m and 9g for variant_48 up to 2h 15m and 12g for variant_56 - Cap_hygro: will take 1h 59m and 10g for variant_48 up to 3h 6m and 17g for variant_56 - Filter: the 5mm height takes 41 minutes and 3 g

If your hygrometer doesn't fit (I desgined it for 42mm diameter and 14 mm height), your silica gel falls through the holes or other issues happens, feel free to contact me. Happy printing and storing! Any feedback is highly appreciated and helps to improve future models. If it worked for you, please tell me your spool so I can make a new page to feature a solution for that spool. If not, please share your problems, I'll do my best to solve them as soon as possible. Designed with OpenSCAD and its thread library. Changelog: - 26/10/28: (hopefully) helpful Images are added. - 26/10/26: Filters are added, see part selection > hygrometer > optional for more info. + extra bins for hygrometer now have a small edge to hold the filter in place. - 26/10/23: The bins and hole-y caps are now print-ready, you don't have to flip them anymore.
