so whats out there for 3d printed drive shafts? are there different designs? ive been modelling slash parts and would like to make a printable driveshaft that would work for one

@Lance_Greene ​ as far as I know the only ones printed printable are the “central deiveshafts” included in the main assembly STEP file. They are the ones used in this video: https://vimeo.com/105538084
They are tricky because they sustain a large amount of stress at the ends where there’s a pin. The only material that would not brake was Polycarbonate and to certain extent Tritan.
