"Mac N' Cheese", a 3D Printed Automaton Illusion

The second of my 3D printed "illusion" themed automata.

Similar projects worth following
"Mac N' Cheese" is my second in a series of "illusion" themed automata. The mechanism uses a single N20 100RPM gear motor driving gears, cams and levers to perform the "illusion" of a mouse consuming a cheese makers cheese.

"Mac" is a cheese inspector, and "Cheese" is his nemesis, and a press of the button animates Mac's ongoing difficulty with Cheese's appetite.

This 3D printed automata is the second in a series of "illusion" themed automata I've been working on. The model was inspired by positivelycreated's "Say Cheese" automaton along with our grandkids "bug eyed squishy frog" bathtub toy.

Do you ever share or sell any of the .sti files for your creations?
Gosh, they are so fantastic.

Hi Pops,

Your comment to Dan showed up in my feed, and I'm not sure if you intended this message for Me or Dan Maloney.

If me, I do publish the .stl files usually on Instructables, YouMagine, Cults3D and MyMiniFactory.

Hi Dan!

I'm finishing 3D printing and assembling the remaining parts, and then I'll publish the design and files.

I've seen similar mechanisms but never was able to get close enough to see how they worked, so I had to reinvent the wheel so to speak.

Thanks very much!

I'd love to see more of the mechanism - not clear from the video how it works. Great stuff!

Hi Dan!

It's now finished so you can view the mechanism!  Hint:  magnets.
