That looks really great! A tip to make it even more realistic is to think about where on the piece (1) there would be more general wear and (2) where a person's hands would most often touch the piece. Spots with more wear (such as edges and corners) tend to get lighter while spots that get handled a lot tend to get darker (from exposure to dirt and oils). Again, beautiful work!

Really well made project, but what is its purpose? What does it do? I'm guessing that the electromagnet coil causes the die to jump around and essentially roll itself? Unfortunately your 3D printed die is not evenly weighted- the only way it could be is if the magnet inside were a cube or a sphere at the exact center of the die. You also may have an undesired effect since the pole of the magnet only runs through one axis of the die. The north (or south) end of the magnet may be naturally attracted to the coil as the power is turned off.You should try an experiment- run the machine 100 different times and keep track of how many times the die lands on each side. I bet that some numbers will come up a lot more frequently than others. I'd wager that the die will land most frequently on the tw…

I'd love to see the results of this experiment!Nice work and well documented project!

Great project! Another option is to use a small cardboard box. Cut a couple of mouse-sized 'doors' on the sides of the box, set the mousetrap, put it in the box and then tape the box shut. Pets can't get access to it but the mice always find their delicious demise! Depending on the rodent traffic I'll sometime put more than one trap in the box. They don't seem to mind going after the peanut butter beside their dead buddy.

To find the exact center of the can bottom, I'd suggest balancing the disc on the head of a push-pin. Once it's balanced, take a cork or something similar to push the can bottom against the point of the push-pin. This will force the push-pin through the aluminum and create a hole at the weighted center of the disc.

So... you just drink the wet coffee grounds? :)

That's a good looking project. Curious why you set the checkerboard below the surface of the rest of the table.

That looks awesome! Just FYI for other potential builders, regular PVC will work just as well and is a little cheaper that CPVC. Nice work.

Seems like it might be a lot easier to just keep the egg carton in one piece and fill each hole with lint and wax. Once the wax hardens you could then cut the carton into individual pieces.
