Object taken from Thingiverse. Took an hour and 10 minutes to print.
Build quality wasn’t perfect. Had to file surface and drill holes.
Layer height = 0.2 mm
Infill = 60%
Supports = none
3d printed the mechanism
Josh recommended Simplify3D for slicing.
I started using Simplify3D for slicing & without seeing it myself I wouldn’t have believed the difference it made in print quality.
Thanks John Rodrigues
