This is a remix of the model linked from Thingiverse.

I modified it to be stronger and more play-friendly for my son who really wanted an Astrobot toy.

Printed with PLA.

Note: the antenna prints OK but it does fall of quite easily if not handled gently.

Printing notes:

This was a tricky print due to the supports needed and the number of colour changes. 

First I tried soluble supports but the MMU2S was useless at reliably feeding the filament through so had to use regular filament.

I first tried using grid supports but they were too hard to remove after the print had finished so switched to organic supports which some tweaked settings (settings saved in the attached 3mf file).

The grid supports were too enclosing and hard to remove:

There are over 500 colour changes required throughout the print and my MMU2S probably needed about 20 interventions to unstick filament and get it going again. Overall it took 2 days to print (I kept it paused overnight as it's a bit noisy to keep going).

To avoid colour bleed between the changes I increased the purge volume between blue→white and black → white to 300mm3.
