Lone Echo's S8 android bobblehead from the centre console of the Kronos II.

The model I test printed was printed at 80% scale at 0.28 layer with 10% infill. Whilst this worked, it was unable to capture detail in the fingers, however at full scale with .2 or .16 layer, this shouldn't be an issue.

For best results print the head in translucent PLA. This way you can add a tiny LED into the head to get the eyes to light up.

Supports are a must on both pieces. Would recommend using tree supports as regular supports make it difficult to remove some parts. Also, with regular supports I'd recommend printing the head with the visor down towards the bed, as this part needs sanded anyway and fewer detail on the sides get trapped in support material.
