Yes, they don’t really exists, until now. In 1978 up to 100 prototype rocket firing Boba Fett action figures were made until several children were injured and one killed by the rocket from the rocket firing Colonial Viper toy. Kenner quickly shifted gears and fixed the rocket to the jetpack.
Bootleg figures were recently produced and I couldn’t help getting a J and L model.

The gear is taken from Media Conversions, I took the basic dxf file, imported it into Fusion 360, extruded it, and
chopped it up using a jigsaw type connection so each piece would fit on my print bed. So far I’m very happy with the result.
I’m powering it right now with a small 12V DC power adapter intended for use with LED strips. However it may be underpowered, the Arduino seems to
reset after continuous use. The DC motor may be pulling too many amps.
