Summary

This is a custom design for a 3D printed 5 axis Robot Arm. I modeled it in fusion 360, 3D model is available on link: https://a360.co/3Zw6ABV.

I also made a Youtube video about this arm: https://youtu.be/DrfbQ5mYfFY?si=TZ1EvpS9oo3ImsmC

I controlled the drivers with an Arduino NANO. </p><p>I did not include the Arduino program here, since it requires custom hardware (custom motherboard and joystick/controller), all of which are not 3D related. If anyone is interested in more details about electronic hardware, you can write me in DMs. </p></div>                <p class="detail-title"><strong>Disclaimer</strong></p>            <div><p>If you try printing this model (depending on your 3D printer accuracy), you might run in some clearance problems. There will be some sanding required with sandpaper or grinding tool to make the parts fit together. </p><p>Also, I did not design the 9G Servo Grabber/Claw, I downloaded it from Thingiverse long ago and can not find original maker anymore. If someone recognizes their desgin, feel free to write me and I will include the thing number. :)</p></div>
