Plantronics BackBeat PRO 2 buttons mod

Make my headphones stupid again!
I've got the plantronics backbeat pro 2 and everything would be fantastic, except I am using them in a bed and that wasn't what good people of plantronics had in mind.
As you may know or not (as apparently I didn't) the "smart" function buttons are on the flat sides of the cups so as you lean on a pillow you will simply press them and beep the next video plays, beep the thing is making a call, beep, beep, beep......in my bed I want stupid BT headphones, not ones that will call police or quick-order pizza when I fall asleep watching the new star trek tv series. (and that is going to happen with the way things are shaping up. Space whales! In a space! Mushroom spores to teleport across a galaxy when you hook them up to a dude!. .whatever the script writers are smoking these days must be potent)
But fear not I have a 3d printer and a caliper and 20 minutes to spare and I am not afraid to use any of those things. And no need for mushroom spores this time
