This design was created specifically for a Rubbermaid 21 cup cereal box (https://smile.amazon.com/gp/product/B00XJRMW5M/), which I'm using as a drybox to store filament. The idea behind this design came from YasiekPL's amazing "Filament dry box dispenser": https://www.thingiverse.com/thing:3626260 This uses two 22x3mm o-rings (22mm is the I.D.), which are probably optional, though that's what makes the cap work well without the need for it to seal perfectly. One o-ring goes in the cap and the other in the back plate. I also used some silicone sealant around the screw holes since there's no sealing on those. This design requires 3x M3x10 screws and 3x M3 nuts. Make sure to check out Madewithlinux's remix of the ball, which was modified to use a pneumatic coupler so a ptfe tube can be easily connected. https://www.thingiverse.com/thing:3850124 Update 10/17/2019: I uploaded a lower profile version of the cap, which can be used if there's no Bowden tube sticking out of the ball: Filament Pass Through-1E-CAP.stl
