I bought a Roku Stick a couple of weeks ago. In that time, I've accidentally pressed the buttons for Now and Sling enough times to decide action needed to be taken.

I used a tiny flat head screwdriver to pry out the two rubber buttons I will never, ever use, then measured the opening using a caliper.

I recreated the general shape of the button in Autodesk 123d design.

It occurred to me while making a quick prototype of this, that I might need to take the button out (should, say, someone figure out how to jailbreak the device and make those buttons actually useful again later), so I created a version of the blank that has a hole in it.

This hole is just big enough for a thumbtack to be inserted, so you can pry out the blank.

I also uploaded a solid version, if you're not afraid of commitment.

Assuming your printer is dialed in pretty well, and prints true to size, you should be able to print these and press fit them in to place.

I didn't have any normal black filament, so I printed mine using ninjaflex.

Also, because the top is slightly angled, I printed these with the top surface on the bed of the printer, I wanted that surface to be the smoothest, and not show the layer across the top. If your first layer sucks, print it right-side up and sand it smooth if you're in to that.

This is a pretty small print... good bed adhesion if you're printing these right side up. Nice flat bed if you're printing on the face.

Shove this in the opening you made when you ripped out the unused buttons.
