Parametric BB-9E Ball Droid

==>Be aware: This is a work in progress!

This design is heavily inspired by James Brutons BB-9E Ball Droid. I do like the ball design he used for this version of the ball droid, but I could not find any designs for it anywhere.

So far I have only designed the ball and printed/assembled part of it.

Printed Parts:

OneThirdTriangle.stl (24x). I have printed these in PLA with 25% infill, no supports and with 0.8mm nozzle (standing up position).
RoundTab.stl (24x)
RoundTab2.stl (8x)
PanelHalf_Open.stl (4x)
GridHalf_Open.stl (4x)
PanelHalf.stl (8x)
GridHalf.stl (8x) or FakeGridHalf.stl (8x)

Optional Printed Parts:

GlueJig.stl (1x)
MillJig.stl (1x)
MillJig.stl mirrored (1x)
MillJig2.stl (1x)
MillJig3.stl (1x)

Remarks:

Despite the maxium cooling I used for printing the OneThirdTriangle.stl parts, they were still slightly out of shape. I used my milling machine and the mill jigs (MillJig.stl,MillJig2.stl,MillJig3.stl), to fix the shape so that the RoundTab2.stl could be glued in place strongly.
I used the GlueJig.stl to glue the parts together in the circular shape. (See also James Brutons youtube video: https://www.youtube.com/watch?v=qtkGU4E6caA)
I have first glued the OneThirdTriangle.stl together and after that did plastic weld the parts from both inside and outside to get a very sturdy ball
