It's surprisingly smooth for a 3D printed gear too. I was worried the gears would be too small for my machine, but it's working great:
What will drive the arm movement? I’m guessing adafruit or arduino, which controls the up and down motion?

Also, would there be thoughts to getting these pieces made in aluminum? Or maybe resin cast?

The plan is to use a 9g servo with a slot on the arm to convert the rotary motion to linear. It's cheap, it's strong, and it's easier than the other options I've tried!

My plan for this project is to have everything 3D printable. I don't have access to an end mill or CNC so I wanted to keep it simple.

onshape is completely browser-based and can be accessed from just about any device. you can open the file and measure any part or export components

Sorry everyone, I had my first child last March and this past year has flown by. I do have this project sitting on my workbench and I have a bit more free time now that he's getting a bit older, but it's still hard to find enough time to keep prototyping and printing. I also recently switched over to Fusion 360 which means I'm using OnShape less and will probably want to translate the project over. Either way, I do plan to keep working on it and hope to have some more progress in the coming months!

I have been working on a separate project that also uses the pca9685 servo board. I have been fighting on the Honus code piece from monsterpalooza several years ago and ported all the Arduino code over to raspberry pi. I got the code up to about 800 lines of code trying to add functionality with a wiimote for lights, motion and sound.

I have been documenting things here:

As far as your light solution this will work directly with the pca9685 servo board: ... WXBMY2HT0C

The elechawk rc switch is a Chinese made unit that I have yet to find one made locally here in the United States. 40 degrees is off and 110 degrees is on. The above link to the amazon product is the form you want.

But that aside if you want help on the coding piece I am game.

And more specifically I was looking for 3-d stl files of the knobs to finish out the print I have from your cad link.

The servo idea with the mechanicals is spot on. Though on my builds I have been moving more towards a belt mounted battery setup using dewalt batterys with a usb phone charger adapter. It makes addressing power needs much easier and more manageable.

If you need any help identifying all the main variant screens from the cartoon, I think I could recap them with some gif, then you can choose wich ones you want to include in your project.
Honestly, I could use a ton of help finding episodes that have both good shots of the screen for graphics and good clean sound samples for each of the PKE meter states. I've located a couple but a majority of scenes have background noise or something that makes it hard to get a good looping sound effect.
We may want to contact the studio and see if we can get cleaner source file cuts or if someone knows who did the special effects for the cartoon that could work too.

I built on based off this main design:

I am going to try and get things even more compact inside. I try to stick with off the shelf solutions so others can more easily follow. Fabricating your own custom doodads, creates its own set of issues when things break.
