I used dye I bought a JoAnn fabrics Jaquardi iDye specifically since it is acrylic. I used their orange and black and just ordered the parts as bright white unpolished. https://surveyorconnect.com/index.php?mode=thread&id=227217 I dipped them in acrylic sealer when I was done.
The 1/4 scale robot is really cool in person, I don't have my Model 6 yet. If you haven't seen the other threads they may help a little

I tried printing a 1/20.5 scale scanner for a no cost ad for a project I am printing. It came out very cool and cheap! The first pic is with some 1/4 scale models and one 1/6 scale Geodimeter Model 6
This was done for a special project hence the weird scale. I think some setup for 1/18th would be kind of cool
I would like to buy one of the robots, maybe two.
