The controls can be done with an Arduino Nano and the SG90 which can be modified for analog position feedback - in this case the max supply voltage for Servo should be 5 V. Pending on the accuratecy of your 3D print the clearances should be adjusted. I loaded the one corrected for my printer in ultra fast mode. (Tevo Tornado 2020); The most unknown is the connecting arm from servo to robot as they are manufacturer specific. You have to figure out how to do it - the assembly is from inside out\nOne important matter is the power supply ,you should use a 5/6 V power supply connected to the board probably the USB won't be enough ( shaky movements).\nThe .f3z file ia basic arm mechanism sketch , by changing the 30 deg and 135 deg angles you can build the envelope of movement."}
