Spool Centre Desiccant Cap

The purpose is to seal off the centre hole of a filament spool in which desiccant can be held. My filament dryers don't have a separate container for pouches or desiccant granules, so this allows the spool to hold them in the centre space while drying thus improving the drying ability of the dehydrator device. Plus filament spools remain dry due to the desiccant when placed in their sealed containers between prints.

For spools that have a centre hole without a lip, set the "Slicing Tolerance" to "Exclusive" which will reduce the model size slightly to facilitate a push fit into the internal diameter.
