Simple adapter to mount a Nema 8 on a Zesty Nimble V1

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:3856292.

Changelog:

1. Added the step files for the shaft coupler and the Nema8 mount for the Nimble V1.

This adapter will let you replace the drive cable with a Nema8 stepper. There are two versions because the Nimble is ambidextrous. Choose the left-handed version or the right-handed version.

There are also two shafts to connect the Nema8 shaft to the Nimble worm-drive. One where the setscrew is screwed directly into the plastic (no insert) and a version where you can use an insert in the shaft. This is experimental and not (yet) a formally supported method.

The STL models are checked and optimised. The parts that need a different orientation to print properly are rotated to the preferred printing position.

With an installed weight of less than 27 grams on your carriage/effector the Zesty Nimble is the smallest and lightest extruder you can buy, it has ample torque and can be mounted in multiple orientations.

The Nimble is available from Zesty Technology.
