Dry Box 1/4" Tube Cap

thingiverse

I was impressed by the Rubbermaid container Dry Box idea shared in other posts. The Rubbermaid 1840750 21-Cup Modular Dry Food Storage Zylar Container is an excellent option. To create snap together spool rollers for 626zz bearings, I designed and printed some using Thingiverse's 2317649 design. This saved me time and effort. I discovered a threaded grommet that mounts without additional hardware, thanks to ukwebb's clever design (note: print at 100% infill). The design can be found on Thingiverse as 2170536. To accommodate the grommet, I drilled out the center so some 1/4" tubing could be pressed through. This allowed me to create a cap to seal off the end of the tubing for storage when not in use. I used PTFE TEFLON TUBING with an I.D. of 3/16" and an O.D. of 1/4".
