the Transmission Thing
thingiverse
This *Transmission Thing* was used to create a [Youtube video](https://www.youtube.com/watch?v=dKxtfmzI6X0) illustrating the basic principle behind a constant-mesh manual transmission. It is a fully functional 4-speed (+reverse) gear box. All are welcome to it. I did *not* model synchronizers - I intend to create them as a stand-alone *Thing* in the future. -------------- Assembly instructions, a parts list, and printing notes are provided in *Assembly.pdf*. *STEP* files are included for the handful of prints that the modeler may want to tweak for optimal performance. (These are generally cylindrical prints with important clearances that your printer may produce differently than mine.) ---------------- It is a *large* undertaking - 72 prints requiring roughly 155 hours of print time (with my CR-10.) It's not the right project for a beginner - or folks with actual lives. :)
