Robot Arm (SG90)

Minimal, meaning very little filament required. Servos connect to frame using friction fit, so your printer will need to be good enough to do some detail on the connections. It all snaps together, meaning you will need to bend the frame out a bit to get the servos to fit in.
It is worth manually wearing the pins (that connect to the frame as part of the joints) to ensure smoother operation.
Have Fun!
