Look, I’m just going to come out and say it… this Giant USB Button is probably too big! It’s 228.6mm x 228.6mm x 120mm (which is 9″x9″ x 4.725″). The thing is, when someone asks me to build something for them, and it seems interesting, I can’t really say no. And I did say “no” this time, but mainly due to the tight deadline. I said I would need about twice as much time as requested and luckily the client came back with “We can do that!” So I got to work…
I didn’t want to screw around with a laser cut enclosure this time, and they basically wanted the Big Button I normally make, but… embiggened. I made this the very close to maximum size I could using my Bambu Lab P1S printer.
So 9″ square (or 228.6mm square) was the size, and the client liked it. I had almost done a button this large about 6 years ago. I gave the client a very high estimate, explaining the custom fabrication that would be needed for a clear acrylic dome, and they were almost on board with it, but luckily passed. It’s years later, printers have improved, and this client was okay with what I suggested.
There’s a large NeoPixel Ring from Adafruit on the inside because of course it has to light up.
Here is my normal human hand for scale. This Giant USB Button just seems ridiculously large. It’s too large! It’s like what, is André the Giant pressing it? (No, because he’s dead.)
Here is the Giant USB Button with a US quarter for scale. The US quarter is that tiny little round thing in the lower left corner.
There is a normal sized USB cable that plugs into the Giant USB Button and allows it to send commands to a computer. I don’t know what the client is using it for because I always forget to ask that question. I’m usually so focused on the project and getting everything to look good and function properly I never ask what it’s for!
Overall I am really pleased with how this thing came out. I had to but a box large enough to ship it since the boxes I usually use are way too small to fit a Giant USB Button. Oh, I also designed it to be parametric. which is handy because I got all the fitting right with a version that was probably half the size. I also made an even smaller version to experiment with different methods of closing the circuit. Again, I had fun with this one.
Finally, here’s an exploded view of the parts, except I forgot one piece! The original design used a piece of clear laser cut acrylic but I ended up swapping it out for a 3D printed gridded disk to save on weight. Anyway, this is most of the 3D printed parts of the Giant USB Button. (I didn’t include the electronics so you can use your imagination for that part.)
