In the newer Pacojet models, the air supply can be turned off via the menu. However, in the older PJ1 model, air is always pumped because the pump is mechanically connected to the motor. This bracket solves the issue by keeping the air pressure release button pressed. As a result, air freely escapes during the pacotizing process without creating pressure.
I printed it using PETG material on a printer with a 0.6mm nozzle. The original model file for Autodesk Fusion is included, so it can be modified to suit your needs.
The author marked this model as their own original creation.
