Not much to say. I had a broken lift arm component. I'm told it's because my wife lifts it from the cupboard by the bowl lift mechansim, but I suspect it's actually from someone forcing the lift mechanism backwards or lifting the machine by the lift arm handle.

Test printed in PLA to verify size then printed in Qidi PAHT-CF on a Qidi Plus 4.

Orientation when printing is a difficult decision to make. One way, the hole for the bar that raises the bowl is the weakest, while the other way, the screw though the handle shaft is the weakest. The screw through the handle shaft is what broke on my original, however, I decided to orient the print so that that screw hole was again the weakest (oriented as in the stl). I tried it the other way (laying on it's side), and the bridging of over the bar hole made the hole slightly undersized. And because it was undersized, it broke when I inserted the bar. It was a little small because of the slight sag while bridging the hole.

60% gyroid infill, 6 permiters, 5 top layers, 3 bottom layers, 0.2mm layer height. Takes much less time to print than it does to find and order the part on amazon and have it delivered. :D.

Drawing in freecad format provided as well as STL.
