Filament Oiler/Duster NO SUPPORTS

thingiverse

This is an innovative oiler/duster I designed as a solution to a severely static-charged spool that was attracting dust from every direction, resulting in partial clogs and ultimately horrible print quality. Print this design on the flat surface featuring the larger hole. All overhangs are 45 degrees, eliminating the need for supports (the solid walls are depicted in blue in the section view). The thinnest walls measure 1.6mm. Cut a piece of sponge or foam into a puck that measures 7mm tall and 15mm in diameter, then squish it through the large hole. Add your vegetable oil (if desired) and push your filament through the funnel side.
