Stronger 3d Printer Marble Machine 3

I had trouble printing this Marble Machine. Not sure if it is my printer or that I had to scale it down to 83% to fit my printer, but the tall thin parts were too fragile for my printer and knocked my print head out of position.

I tried to reinforce the smaller bits, which worked for me. See the Photo. I then added a few more of the same elements just for aesthetics. I uploaded the stl file with the visual additions, but I didn't print this stl file version (since it takes so long on my printer). Designed in TinkerCAD and "repaired" in 3D Builder.

This works with the original screw and other parts. I didn't remix those, but had to print the screw with supports. I scaled everything in Cura to 83% and used 8 mm BB's.
