    I came across this build by lorinczroby on Thingiverse, and I think it could be a good candidate for a low-mass direct drive for the tool-changer:

    They also made a remote direct drive similar to the nimble, but they say this planetary gear-box doesn't result in print artifacts resulting from high-gear ratio worm gear setups.

    See the bottom of the post for build images and videos of the extruder working.

    I'd love to hear what ya'll think!

    For a lot less hassle you could get a Bondtech BMG with a pancake stepper motor that is 215g (75g BMG, 140g pancake). My question would be is the 77g savings worth it?
