Look here. http://wingovations.com/gl1000-new-parts/4579471065

Some guys have used a nickel coin for replacement. Just be careful with the glue there is an air duct up there.

I make these "buttons" with my 3D printer using an ABS filament. Installing the button can be a challenge because it is easy to damage the cap. When you press the button into place, a lot of pressure must be applied to the center part of the cap and it is easy to warp it, which results in the center "rod" to be misaligned. If this happens, you will have to replace the cap. My solution was to design and make a special tool with my 3D printer to keep the center rod perfectly aligned. The tool looks similar to a doughnut and slips snugly into the bottom of the cap cavity around the rod. This causes the pressure to be kept evenly on the rod and prevents it from moving. I use a vice to carefully press the buttons into the caps. I may take a picture in a day or so to help explain this.

Here are some pictures of the parts and tools that I have created with my Lulzbot Mini 2 printer. The blue part protects the cap from being damaged when you press in the button and it is made out of PLA. The red cylinder tool is used to press in the button using a vice or a press and it is also made out of PLA. The button is made out of ABS plastic. The red flat O-Ring is placed between the cap and the button to help create a tight seal and also provides an air gap for the inner part of the cap. It is made out of TPU.

I recently tried PETG and I like it better than ABS because it prints cleaner. It is tough stuff.
