This was designed to make the task of putting on the o-ring on the DIN retainer easy when servicing a Scubapro first stage.
Simply cap the bullet on the retaining knob and slide the o-ring down into the groove.
The tool eliminates the need to stretch the o-ring over the threads of the part, preventing potential damage.
- Print in the orientation provided.
- Since the first layer is rather small it requires good bed adhesion.
- Use 0.20mm or 0.10mm layer height.
- I've had perfect results with PETG, 2 min perimeters, 3 bottom and 4 top layers.
