If you’re a mechanical engineer with some free time and access to a 3D printer, what do you do? Obviously you take a classic transmission like the five-speed manual from the Toyota 22RE and replicate it in scaled miniature with a 3D printer.
That’s what Eric Harrell of Santa Cruz, California did. The transmission, of course, is meant to attach to his 3D printed replica 22RE engine. The engineer has put his plans for both the engine and transmission on Thingverse, an open source trading site for schematics to replicate items on 3D printers.
Most desktop 3D printers can make the transmission, says Harrell, in about 48 hours and assembly will depend on the user’s skillset. Here’s the engine and transmission in action:
