Final Project
My final project is a small CNC machine that houses a Dremel for the spindle. I chose this project because it provides a solid foundation for many of the mechanical, electronic, and design concepts we will be learning throughout the course. It will give me experience that I can carry into other projects that require similiar components, such as a pen plotter or even a larger CNC build.
I created the sketch below from what I found online. DIY Dremel CNC
I had issues with sketching (I'm not very good) so I traced the outline of the DIY Dremel CNC and filled in the rest.
For week 02 I started working on customizing the compact CNC machine to handle a flexible shaft as opposed to the heavier Dremel body. The shaft will be much lighter than the body, but it presents challenges in itself with how I will clamp it down to prevent wobble. The body is tapered and after a discussion with Claude AI, he suggested that I create a V-block mount.
During Week 6, I decided to change my final project from the compact CNC machine to a motorized automaton Manta Ray (reference: manta ray). The compact CNC was beyond my current skill level, but it remains a build I plan to tackle after Fab Academy — I'm a woodworker at heart and have been pricing CNC machines for years, so it will remain on my agenda.

I have the sketch for the manta ray that I took from the video and brought it into Adobe Illustrator and traced it.
I sliced it up as directed by the original designer and cut it on the laser cutter.
The next steps are to create wing hinges so that when the wires are connected underneath, the ray will appear to be swimming through air.
I also spoke with Dr. Taylor and Garrett about potential modifications — ideas included adding a remote on/off switch and a music-activated sensor in the electronics.
