Hi Po, Thanks for sharing your design. Are those the Lock-On Shorty Grips from Lizards Skins? I just ordered the Lock-On Bearclaw grips and am hoping they aren't too long, or I may have to return and get the shorties.

I am 3D printing the ptt button insert and am using a URTONE UR168 momentary push-button. I will share my design once it is complete. Travelling this week, so hoping to finish it up early next week.
