I made this silica gel bead container to fit at the bottom of my filament dry box underneath spools. The lid lifts off the top and beads can be filled in.
You need 2x m3 heatset inserts and 2x m3 screws (I think maybe 6 or 8mm?).
There are little clip on feet that keep the container off the surface to let air flow through the vents even on the bottom.
STEP file is included so you can easily edit the model in your own CAD without resorting to hacking STLs.
The author marked this model as their own original creation.
