For a few projects now, I’ve needed closed timing belts of a specific length. Rather than buy them and pay high local prices, or wait for a month for them to be delivered from overseas, I’ve started 3D printing them using nylon. I used nylon to print the flex spline… Continue Reading 3d printed timing belts

This means the eccentric, needs to be a dual eccentric… As there are now 2 cams, this means twice as many… Continue Reading 3d printed Hypocycloidic gearboxes IV

This will include… Harmonic, Hypocycloidic, and Swiss joint (not really a gearbox) The key requirements for… Continue Reading Robot Arm Gearboxes
