Silica Gel Desiccant Holder and Roller for Rubbermaid Dry Box

thingiverse

Finally got around to making a better roller for my dry boxes that actually works as intended. The bottom is a snug-fitting silica gel holder and it doesn't even need glue on the arms, although I recommend adding a small dot on the inside to ensure everything stays snapped together over time. I used supports for the taper on the 4 leg pieces, which also got a light sanding after support removal. The rest of the pieces didn't require any extra help. For the last couple years, I've been using my other filament rollers but they haven't worked well with wider rolls in the rubbermaid containers due to their narrower curved bottom and how the rollers sat. This new one will fit rolls up to the width of the container without any issues. There are 4 STL files available: the box bottom and its lid, a leg or arm to hold a 608 skateboard bearing for the roller to spin on, which requires 4 legs and 2 rollers if you haven't already figured it out. I added a V2 bottom file that has nubs on each end to keep the lid in place. Oddly enough, all 4 arms were not as snug in this print and definitely required taking the time for a dab of glue. The same file was used, but since I print in the garage, I can only guess temperature and/or humidity may have been a factor. A first bottom shell got sliced with supports in those leg notch holes and had to be cleaned up just to fit the arms. The next 2 snapped nicely together with play but tight enough that the legs didn't fall out when repeatedly inserted and removed from the rubbermaid container. So basically, without changing the dimensions of the leg to body notches, prints have varied from needing a light file to being somewhat loose.
