It's impossible to make a perpetual motion machine with magnets because magnets go bad. A magnet is made of iron, and in the iron the atoms are "relaxed". Don't ask me how, but to make a magnet, you need to "charge" the particles. Eventually, the particles relax again, and the magnet dies. How long depends on the type of magnet and the usage. So, in conclusion, unless you could get enough power to control a "magnet charger" after 100 years or so, you can't do it. you can, however, make a really long lasting motor.

I would welcome anyone with 3D printing experience who wants to help out with the case. I have one at the local makerspace, but have never used it. Also, I wanted to mention something about the magnet configuration. From what I can see, you can get either bar magnets or ring magnets. There are a lot of different north/south configurations, but only two that i can see as helpful for this.
(Sorry, couldn't find a bar magnet diagram)
I'm going for #2, Just put the other ones on there because
-Bars around Bars (arrange the bars in a ring in the center, a ring on the outside
-Pros: Bars are REALLY easy to find
-Cons: Keeping a structure on that would be like REALLY hard
-Bars around Radial
-Pros: Bars are easy to find, somewhat easy to setup
-Cons: Bars need to be held together, Radial hard to find
-Radial inside radial
-Pros: Simple, Clean
-Cons: Radial magnets are hard to find, custom orders take a while

I ordered my magnets from https://www.xump.com/Science/BarMagnet.cfm, 50 cents is really cheap, and i need a lot of them. I decided to go for the blue one in the details. I was going to drill a hole in the middle of 8 magnets, and bolt them to a piece of plastic in a circle. Cut the middle one in half, it won't affect the polarity. Countersink a hole for the rod, and attach it to the magnet. Hold the rod in place and leave it room to spin. I'm pretty certian it should work, now to research waterwheels..
