Summary

This Transmission Thing was used to create a
Youtube video
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. :)
