Nozzle for Rechargeable Vacuum Pump

This nozzle is designed as a replacement part for rechargeable vacuum pumps used with vacuum storage bags commonly used for filament. The original seal on my pump cracked, making it useless. Rather than disposing of a perfectly good pump, I created this model to restore full functionality. I also have another version that is entirely 3D printed with TPU for this pump.Print this part in a rigid material with many walls/solid. This is to ensure that it is air tight and will function well. Add the large O ring from the original nozzle to the groove on the bottom of the replacement nozzle. A replacement O ring is included. Print out of TPU.
