I liked the design of "The Ultimate Spool Holder Dry Box" https://www.thingiverse.com/thing:2929701 but unfortunately i couldn't find a matching box so I meshed up this Project the concept of the "Filament Dry Box for 3-4 spools" https://www.thingiverse.com/thing:961881.
The parts will fit for any box. You only need 4 608 Bearings / Spool and 2 Rods Diameter 8 mm (smooth or threaded, it doesn't matter, just use what suits you the best ;)).
I remixed the Rod Holders from the Spool box to improve their Strength and remixed the Filter Taps from The Spool Holder Dry Box that its easier to screw in the bowden fittings and to make the filament slide in easier.
The "608-Slides" from the Spool Holder Dry Box had to be printed in two parts and had to be glued together. So i remixed these to a print-in-1-piece and changed the bottom to improve strength and made them easier to print.
Printed in rigid.ink PETG. I recommend printing the Sliders and the tap parts with at least 5 perimeters and 100% infill
