I'm guessing if you put the first pivot arm on top and added ribs to it, it might be more sturdy. then add ribs on the lower part of the second pivot. Just super glue some more plastic pieces to brace it more. Pivot control looks great but i cant imagine Z axis bending so much would make for accurate positioning. Maybe within a 1/2" inch. Not bad though, this is probably how i would make my first one, except maybe more duct tape :) i've actually been wanting to make one but i know it would come out like this. so i've waited to figure out a more robust solution. The more sturdy i think about my design the more i think i need stronger stepper controls, which are costly. or high gear reduction for better accuracy.
The center of gravity is not in the middle but rather too far back, which affects the precision of the Z-axis due to the weight of the two pivot arms in the front. The materials used in this video are mostly recycled, so there are many lacking elements. Thank you.
