About the Print
- Printed with PLA on a QIDI X-Plus at 0.4mm resolution.
About the Hopper Brushes
-I designed the Hopper/Brush unit to use springs, but the weakest ones I could find were still too much for the weak stepper motor.
- Instead, for each, I cut 1 1/4" of 1/4" clear heat shrink tubing, and used scissors to make four cuts in one end to flare the ends making a sort-of brush. See the pictures.
- Right-sized paint brushes might work as well if they can be made to stay in place.
