[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.

The metal pads in question seem to be far too thin and structurally unsound, as one can readily spot, their cross-section is dwarfed by the cross-section of cables soldered to them. This would create a segment of increased resistance and heat loss, exacerbated by any flexing of the thick and unwieldy cabling. Due to the metal being so thin, the stress points seem quite flimsy, as one of the metal pads straight up broke off during disassembly of the connector.
