Just finished the newest version of the remote, with no need for inside bolts, room for a wrist strap and some minor changes that should improve the overall quality of the remote.
I have been trying to solve the "dead zone" issue with the tactile buttons, however, I have not found a solution. Instead, I have bought some new buttons (12,6mm micro switches) and made room for them, which works much better. However, the previous tactile buttons should still fit perfectly.
Will be releasing/updating my Thingiverse project tomorrow, so you guys can try out the design
Thanks for the support!
