Interfacing a shaft to a 3D printed gear doesn’t have to be tricky. [Tlalexander] demonstrated a solution that uses one half of a spider coupling (or jaw coupling) to create an effective modular ...

Flexible couplings couple or connect rotating members such as motors and drive shafts while allowing misalignment in either angular or parallel offset orientation. Sliding blocks are slotted or jawed ...

With a vertical, or sometimes called a flange-mounted motor, the hold-down bolts are near the drive end of the unit and will usually be mounted with the coupling end oriented downward. Conversely, ...
