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.
