Oldham Coupling

thingiverse

The Oldham coupling, ideal for eccentric shaft connections like in Moineau pumps, offers reduced height and space requirements compared to others. I'm incorporating it into my Moineau pump project, but its versatility makes it suitable for various unaligned shaft connections. Similar functionality is provided by Schmidt-style couplings with the same height. The motor end of the shaft features a flattened design to optimize torque and rotation speed transfer. The bottom end has no specified hole or connection type, allowing customization to suit individual needs. If you'd like different bottom connections, feel free to suggest them, and I'll add some variations (in .stp or .ipt format).
