Silica gel container

A container for silica gel in the form of balls. It is designed to be inserted into the center of a filament spool but can also be used for other purposes.

They are connected by a thread that is loose enough to be screwed in even in case of inaccuracies. Diameter 50 mm, height 64 mm. Flange diameter 70 mm.
