Drybox Desiccant Tin Holder

thingiverse

A quick and dirty tray that screws (or tapes) to the lid of your drybox to hold a tin of silica dessicant (https://www.amazon.com/dp/B08NCZRHV2 is the one it was designed to fit). Because they change color to indicate end-of-life, this design lets you check at a glance without opening the dry box. An included OpenSCAD file can generate versions for tins of different sizes; note that it relies on the BOSL2 library for the repeating pattern on the bottom of the tray, so you'll need to grab it to customize things. See https://github.com/revarbat/BOSL2 for details.
