R2-D2 Dome Pie Hinge (modified for less support)

This is a remix of Matt Zwarts Pie Hinges for R2 Dome Mechanisms.

I did not like the need for so much support so i cut these apart and modified the base significantly, so you can print with minimal support/fit more on a print surface.

I originally cut off the back end not knowing it was for cable managment, but kind of liked it due to it being smaller, so i included both that and the one with a better arch and the removal of an overhang so you can print with only base supports (picture above shows support block zones.

I also increased the hole size that connects the base to the Pivot to 3MM to accommodate for 3mm bolts.
