[Scott Prints] had a familiar problem. His garage door opener was boring, and rattled around annoyingly in his car’s center console. This was obviously a major issue that needed to be dealt with. His solution was to install an ejector seat. Er, well, an ejector seat button. At least, that’s what it’s labeled. (That’s sure to be a great conversation starter for passengers.)
The end result looks slick and combines several build techniques. He started by taking measurements and 3D-printing a test piece for the center console nook. Turns out, that’s a more complicated shape than it seems. Rather than try to measure the exact angles and radii, Scott turned to the tried-and-true method of fiddling with the parameters and printing a second test. Close enough.
The coolest and most challenging element of the build was engraving and cutting the aluminum plate that forms the visible part of the build. Turns out, the online recommendations for milling aluminum are laughably optimistic when you don’t have an industrial CNC machine. Slower, shallower cuts got the job done, albeit slowly. A red paint-filled marker made the letters pop. The guts of the donor garage door opener are fitted into a 3d-printed shell, and then a Big Red Button threads into the print, holding the whole build together. A bit of solder later, and the project is done. Simple, effective, and very stylish! We approve. Come back after the break for the build video.
And if you need more garage door opener hacking, We’ve got you covered. And getting started with a home-built CNC? Yeah, we’ve got that too.
Needs a guard to prevent inadvertent ejection :-)
Yes, like the pop top on 007’s shifter!

To avoid accusations of discrimination, there should also be a button to eject the driver.
Mine is hidden in my gear stick
Could have called it a “panic button”.
Ha. Like it. My garage door opener was rattling around the other day irritating me. Hmmm. Needs a covered ‘arming’ switch beside it :) . If armed, the button lights up, pressed while armed, door goes up … or the passenger….
Regarding the milling problems, an endmill designed for aluminum & some cutting oil could help a lot.
better still, a specialized text engraving endmill, also with oil.
Having done a lot of this, I think a two flute ball end mill looks best in aluminum. If you’re using something like scorchworks’ f-engrave software, v-bits can make a really nice engraving because his software manages the multipass stuff required to get good sharp edges at the corners of letters. But for ease of use, a half round looks so nice.
Just look them dead in the eye, hover your finger over the button and say, “Don’t ask again”.
I always figured that an airbag could be repurposed
as the main driver in an ejection seat.
Guy at our airport has a military ejection seat mounted
on rockers in his hanger

GIR (Invader Zim): “What’s this button do?”

Nice Job
