<p>This construction is powered with some small electronics therefore there a multiple non printable parts.</p><p>the parts non printable parts are as follow.</p><ul><li><strong>continues</strong> Servo &nbsp;motor (I used a <strong>TD-8120MG, </strong>but<strong> </strong>size is same as <strong>MG996R</strong>). C<i>ontinues indicates the type of servo you should get.</i></li><li>ISO M3 nut and bolt</li><li>Small electronic circuit <i>(Depends on servo)</i></li></ul><p>&nbsp;</p><p><i>Print settings&nbsp;</i></p><p><i>Printer: Prusa MK3S+</i></p><p><i>material: PLA (I used Transparent red and glow in the dark because i had that laying around)</i></p><p><i>Supports: not needed for any of the parts</i></p><p>print “hanger” 5 times</p><p>&nbsp;</p><p>For the electrical circuit I used a very easy circuit that would output a 5V PWM signal.&nbsp;</p><p>I used a PWM module<i> (https://www.tinytronics.nl/shop/en/switches/mosfets/pwm-mosfet-controller-board-5v-35v-5a)</i></p><p>You can use a Arduino to power servo motors (but check the voltage use of the servo and the amount the Arduino can deliver. A Arduino Uno, MKR, mega etc. can deliver up to 5V volt but the nano can only deliver 3.3V!)&nbsp;</p><p>&nbsp;</p><p>If you're unfamiliar with Arduinos or servo's this is a pretty clear guide for how to do it.</p><p><a href="https://www.instructables.com/Arduino-Servo-Motors/"><i>https://www.instructables.com/Arduino-Servo-Motors/</i></a></p>
