Mantis Stereo Microscope Yaw Hinge Bracket

This is a Yaw Hinge for a Mantis Stereo Microscope (original P/N 187-C-0107). This piece commonly breaks, and parts are no longer available for the original Mantis from Vision Engineering. When I purchased my Mantis, this piece was broken and had been epoxied back together... then that broke one day while using it, so I epoxied it again. That failed a couple months later. So, I decided to design and print my own replacement part.

I designed it in two pieces, since the top doesn't really add any strength, and would be a waste of time/support material to print as one piece. The top just snaps into place, and when the bolts are in, the top is captured so it can't come out. I also attempted to strengthen common failure points.

Unless you have a good temperature controlled chamber, I'd recommend printing this in PLA. I printed mine in (natural) ABS on a Creator X (clone) with a plexi window and hood... the chamber stays around 50C with no drafts, but I still had some warp
