My printing of the dispenser module internal failed because the waterhose connector has only a very small connection surface to the printing bed.
Everytime the main module and the waterhose will filled up the printer pushed the waterhose a small step and so it would not work.
To solve this problem, I added a small support to the waterhose connector, so the connection surface to the bed will be more stabilized.
I printed everything with a 0,6 nozzle.
Printed in PETG
0,6 nozzle
Prusa MK4
Printed with 100% infill
3 Perimeter walls
The author remixed this model.
Support for Waterhose connector has to get more connection surface on the printing Bed
