Poseable hands for Dummy13. You will need the fingers from Alioth's poseable Lucky 13 hands. They are currently scaled for 500%, but should function down to about 200% (40% of this model size) scale if your printer is dialed in. If you're brave, 100% might be possible with a very small nozzle, and very good adhesion, or maybe an SLA printer.
UPDATED (12/26/23): New version includes integrated knuckle pins, so only Alioth's fingers should be necessary. Some support may be necessary for the thumb.
UPDATED (12/28/23): Updated again to make the integrated version easier to print (no supports, no small contact patches.) Also added runner/sprue/kit card versions of the fingers because they can be tricky.
Updated (1/9/24): Apparently I exported the wrong file and put this out with no thumbs! That is now fixed.
The author remixed this model.
I created a Dummy13 hand with compatible knuckles for Alioth's jointed fingers.
