An automated disc launcher for your RC or other projects...

Everything is oriented as it should be printed. rackteeth printed separately (and orientated) for strength.
Align and superglue the rackteeth to the midsection.
Align and HOTglue the motor to the topsection.

You'll need 1 TT geared motor and 4 m3 screws and nuts.

Depending on rubberband setup and If movement seems jaggy at the end of the momentum (when band is pulled back), you could also cut one tooth of the GEAR off. See last foto, make sure you cut the last tooth out on the GEAR.
