The published Chube Integration model leaves a lot to be desired. This is a reverse engineer of the Chube using the published integration model from the Chube folks as a base. Everything is determined from publicly available pictures, video and discord messages. It likely has some errors as I had to guess about several aspects. However the mass and Center of Mass are within 1% of the integration model, so that's close enough.
Heater and Thermistor sensors are here too, just hidden in the published F3Z
I have published a printable without supports version here:

The author remixed this model.
Reverse engineered from publicly available images. I didn't even have a Chube when I made it.
