Massage gun part for calf

If you're a runner, you probably know how your calves can hurt after a long run. I designed this part because I wanted to massage my calf over most of its width at once. I had an original, similar part from a massage gun manufacturer, but it was too narrow for my enlarged calves.

The tip of this part (which goes into the gun) is 18.6 mm in diameter. It should fit all popular massage guns.

If you need a different size, you can scale it down by doing simple math.

Ie. You need a 16.5mm in diameter then

18.6 = 100%

16.5 = x

—

x = (16.5 * 100) / 18.6 = ~88.71%

—

So you have to rescale my part to 88.71% i X and Y axis.

These rings should be printed from TPU. I used eSun TPU-95A, which works very well with my printers. It's hard to get them in place, but with a little help from round nose pliers they fall into place.

If you don't want to print with TPU, a regular rubber band should get the job done.
