Dry Box PVC or Rod Holder

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:4695952.

Holder for a 1 and 1/4inch PVC pipe to hold rolls of filament in a dry box.

These use a 5MM nut and bolt (used soldering iron to push the nut in).

Mark holes on your box and then drill them out. It creates an airtight seal, but you could add something between as a gasket of sorts if you don't feel that yours is.
