When most of think us of internal combustion engines, we think of pistons exploding in a beautiful dance, with a crankshaft turning linear motion into circular motion. It’s a sight to see, and we can even print out such an example, courtesy of sirmakesalot.

However, there are other engines out there, and none perhaps more interesting than the Wankel engine. ROBK636 has created the engine rotor (as a fun keychain!) of this unorthodox design. Known perhaps most famously for being the engine of choice for the Mazda RX-7 and RX-8 sports cars, the Wankel engine has a place in hearts of many a gearhead. We thank ROBK636 for bringing this keychain to Thingiverse, and I hope this is just the start. How long before I can print out an entire assembly?
