Hey Will!
You say you put the Beetle in the freezer? Interesting, why did that help the wheels to loosen up?

Things tend to contract when they're cold and expand when they're hot. I just hoped the axles and the holes in the car would contract away from each other. It seemed to loosen them up enough that I could get them moving.
I've tried it on three prints and it's worked on two of them, so I figure it's at least worth trying.

Theoretically, everything would contract by the same factor, in the same direction, so the size caused by the freezing would not really make a difference.
More likely either the contraction and expansion caused stuck loose powder to loosen up a bit more. Or the cold made the axes less flexible, making it easier to apply force to loosen them.

I suspect that the geometry of the objects involved might make things a bit more complex than you're assuming, but I don't know enough about this subject to be absolutely certain of any of this. All I am certain about is my wheels roll and I'm happy about it!

Ouch, yes! But also pretty amazing to hear of some of the unexpected post-processing techniques people have unlocked.
Do any of you guys know any other methods that people have discovered recently?

Cool project! I am going to try the freezer idea today. My most recent design SHOULD work according to the design rules, but its stuck...
