Water cooler/beer tap valve cusp stem

thingiverse

This unnamed part is crucial for a cusp seat assembly in a water cooler/beer tap valve handle. The bottom ring fits into a gasket seal within the faucet, while the valve handle slips into the notched upper area. This specific tap hails from a beer tube and is quite generic; however, adjustments might be necessary for other handles. 3D printed at 110°C bed temperature and 230°C hotend temperature using a 0.5mm nozzle in ABS filament, the part has two perimeters and 90% infill. Print speed was capped at 40mm/sec. Due to pressure applied on both ends during operation, strength was an issue, necessitating slow printing for better adhesion while maintaining cooling for shape retention. The part was printed horizontally with support, ensuring force acted in line with the plastic's grain, preventing the first print's failure when removing supports between rings in a vertical orientation.
