Guitar Pickup Button Adapter V2

This is an update of my first design: https://www.thingiverse.com/thing:1087912

UPDATE: The little retainer kept getting lost or broken. Redesigned to eliminate the retainer and to make it smaller and lighter. It now snaps onto the pickup button.

This is an adapter for a guitar pickup button. Generally, because the 1/4" (6mm) plug for the guitar cable goes through the middle, the outer diameter of the strap button is much larger than normal. This makes using a stock guitar strap a pain. You can either cut the button hole bigger in the strap end, or use an adapter. This one is easy to print (about 6 minutes) and is easy to use.

To install, slip the larger circle over the pickup button, and pull until the smaller diameter is seated in the pickup button. I had to loosen my strings and pull the pickup back through the sound hold to adjust the inner nut. Not fun, especially with a 12 string. (Use an old guitar string to guide it back to the sound hole, and then back out
