Vòng Giữ Khô Cho Cuộn Filament (Spool Dry Ring)

This Dry Ring fits around 1KG Spools of filament. You fill the ring with dessicant and clamp it around the spool. 

   When I was putting spools in vacuum bags I noticed that the dessicant in the center of the spool was not keeping the filament dry. I decided to create a ring to clamp around the filament so that it would be in the correct place.   

Print with support just under the hinges. I print in PETG for some flexibility. I filled the ring with dessicant using a funnel. Happy Printing!
