So you've been busy tinkering in the lab all day and forgot to get something for that someone special. If you've got a nicely leveled 3D printer you could quickly print one of these cute keychains... of course you have to say something beautifully sappy like:
... "You're the gear on the left and I'm the gear on the right, and the gear at the bottom is our love that keeps us in sync..."
And if that doesn't work, well good luck to ya!
Inspired by Emmett's awesome single print Gear Bearing, his Heart Gears (which takes a while to print and put together) and Umake's Gearbox Keychain.

Takes about 40-60 minutes to print. Single print in place, no raft, no supports.
Make sure you print it with the gear faces down.
I have had the best luck printing this in ABS on a Makerbot Dual and 2X, but we have had some nice prints from our Ultimaker in PLA.
I've been printing with:
0.2 Layer Height
NO SUPPORTS (pfft)
NO RAFT (ain't got time for that :)
