1/16 Scale FrankenDiff

Something just didn't feel right to me, I had play in the pockets up and down, but not from front to back. So I got out the Opti-visor and gave things a look-see.

In most of the pockets there was a booger about 1-3mm wide in what would be the top of the arch when the pockets are printed. This area would be the bottom side of a bridge when printing. My printer does pretty good, but the bottom of the first layer of a bridge is NEVER pretty.

My current plan is to increase the radius about a 0.5mm in that area. I'll still get a booger when the printer bridges in that area, but the booger shouldn't be touching the bearing any more. And since I'm measuring about 0.2mm of total play I'll reduce the radius of the bearing pocket by about 0.1mm.

I've got a problem with the pinion housing's print too, turns out I'm trying to print a circular opening in a horizontal surface in mid-air. (Without support) That NEVER works out for me - should have seen that one coming.
