Parts For an old thumper

I have this old massage device, Thumper V1- very powerful well-made, and was great for muscle pain, but over the years one part has worn out or rather just disintegrated over time. abc part that’s red

I called the manufacturer, they no longer make the part, so I looked into having it made, it’s a very simple design, but couldn’t get any answers from company’s contacted.

So any other ideas or places I could look into that either have the part or can make it would be great.
The rest of the device is in great shape, shame to toss it out for a piece of plastic/rubber.

Thank You.

Hi! Unfortunately we do not know where to get that part. Our massage guns have updated and different parts. Sorry we couldn’t be of more assistance!
