3 Axis Robot Arm Mrk1

3 Axis Robot Arm – First Version

This is the very first version of my 3-axis robotic arm project.
For this build, I decided to reuse my older gear reducers, which you can also find on my profile. They have proven to be reliable and efficient, making them a great starting point for this design. This arm is mainly intended as a test platform for exploring movement control, mechanical stability, and modularity.

Future versions will be coming, with improved mechanics, enhanced precision, and potentially additional axes or attachments to expand its capabilities. Each new iteration will build on the lessons learned from this first prototype.

Technical details:

• Powered by NEMA 17 stepper motors for smooth and precise motion
• Requires M3 screws, M3 nuts, and M3 heat-set inserts for assembly
• Designed with reusability in mind — compatible with my previously shared gear reducers
• Easy to print and assemble with standard tools

This first version is perfect if you want a functional base to experiment with or to customize for your own projects. Stay tuned for more upgrades and design improvements!
