Here is an update on my PTT switch and control grip replacement. I created a 3d modeled/rendering and 3d printed the button/grip adapter. The 3d printed adapter has with M16x1 threads to allow the PTT button to be threaded directly into the adapter, which eliminates the need to use the provided nut. I removed the control sticks, removed the old grips and PTT buttons, removed the control stick paint and repainted with gloss black. The new button is due to arrive today and the wiring/connectors will arrive tomorrow by Thursday. I chose 4pin JST SM connectors which will allow easy removal of the control stick in the future without the need to cut the wiring. Heat shrink will be place on the wire near the control stick exit hole to protect the wiring.
Total weights:
LizardSkins Bearclaw: 105 grams (x2)
3D Printed adapter: 4.12 grams (x2)
Button: 22 grams (will confirm actual weight when the button arrives) (x2)
Here are a few pics of the progress:
