20mm pole bracket for filament storage box
thingiverse
This is a bracket I used to make a filament dry box out of a plastic storage container (Sterilite #1925) and a 20mm dia. metal pole (left over from a shelving unit). Unlike the other rod brackets I've seen here, these are designed to mount with screws going from the outside in, rather than from the inside out (which wouldn't work very well going into plastic this thin). Instructions You will probably want to use a fairly high infill percentage, so that the screws have something to bite into. Drill a pair of holes in each end of the container, 30mm apart assuming that you didn't rescale the design. Attach using small wood screws (I used #2 x 3/8") and washers.
