The parts I needed to use this for the #FilaMecanum project are back to printing after a little battle with some printer issues.  About 70% of my four transmissions are done, but I still don't have a single one actually assembled.

I have been saving the planets for last as I am going to do those in nylon, and I don't have a lot of that to waste on purging.

<EDIT> All the PLA parts are done and I started on the nylon ones. 

Some flailing ensued, but I'm now printing them.
