I have bought without this button; seller has not found it, so I designed one, based on picture found on inmotion site.

If you found this useful, please donate what you think it is worth to my paypal.me. Help cover the time of design.
Thanks, Enjoy!

Print with 2 layers bottom and 2 top with 10-20% infill. If not - it is too hard.

There is a small push-in hole 0.5mm to be done with something hot (I have used drill fi 6 and hotair) on the bottom side where tact-switch is seated; if not, the tact switch underneath would be pressed all the time.
