Y-Axis Belt Tensioner for Original Prusa MK2, MK2S

I wasn't satisfied with rotating the motor to tension the Y-Axis. Of everything I looked at or considered, this seems like the best solution. I remixed this model, making the opending wider to fit the belt pulley for my MK2S.

I used an extra bolt that came with my machine. That works but a hex (not allen) bolt would be easier to work within the tight proximity to the front LCD screen on the MK2 Printer.

Brukj has an excellent pdf instructional document loaded with the original file.
