I tend to use shopping trolley release keys - and use that for a test file..

OK, I must ask, what is a trolly release key?
In my mind it's a key to release a shopping cart from the rental lines. No?

I'll give pet-g a look. From what I've been reading here, it doesn't appear to be a favorite filament of some.

We want some flex in parts such as the main frame. So far we have the frame, and have finished the first leg sections. I'm printing the second leg sections now. Electronics mounts are next. PLA has been working very well for everything.
Frame length is 212mm long. This thing is going to be a pretty good sized bot crawling around the floors.

PS I agree with Aardvark that PET-G is nicer to prinf and gives better results if you aren't bothered with chemical compatability.
