Platform Jack with bolts

Truly amazing model. But to print it assembled you need a finely tuned printer. I have not. My first try actually worked, but the knob broke off, and the long bridges failed, looking messy. But I really want this one. My version craves a lot of assembling, 16 bolts, M3x12 or M3x10 and a good screwdriver. This version is smaller than the original. If you scale it 133% you should be able to use M4 bolts instead. I have not tried that.
