Yup, link worked fine. Lets figure this out.
You've got a M3D, which as /u/Keebie81 said isn't the best. If I understand it has proprietary software which could make things difficult, but we'll see what we can do.
So first off lets get some background information. What kind of filament are you using? ABS, PLA, or something else? Can you get us some idea of what settings you're using? Take screenshots of every setting page you can find so we can see what settings you have now and what extra things we have to tweak.
Just taking a look at it, it seems like you're having adhesion problems (which can be fixed with treating the print surface appropriately and fine-tuning your Z-height) and warping problems (which are usually material and temperature related).

We can try to take a crack at adhesion first. There's three big parts to this: making sure you've got a good surface, making sure the surface is treated with the right stuff to get maximum stick, and then making sure your nozzle is close enough to the printer to get the filament down right.
On the first point: painter's tape is a good, cheap bed surface that seems to work great for a lot of people. I use this stuff. There might be blue painter's tape somewhere in a janitor's closet or shop room somewhere, but you might have to go get some yourself. First clean off your bed surface with alcohol and a good cloth that won't leave anything behind, then lay down your strips nice and flat with no air bubbles and as little gap between them as possible. I also use a putty knife to smooth it all flat.
On the second point: getting your bed surface (and z-height) can be enough, but you can get extremely good sticking with a good bed treatment. There are two popular methods: glue sticks or hair spray. (Take a look at the "Customers who bought this also bought..." for the hair-spray, it's not what you'd expect for a beauty product.) I use that hair spray, and spray a cloth which i then wipe onto the painter's tape for a nice, even coat. You can pick some up at CVS, and I'm sure you have glue sticks laying around at school.
Finally: adjusting your z-height. This is going to be slightly hardware dependent so I may not be a ton of help here, but you have to be really precise in where your nozzle homes to. Heat up your printer (so it's thermally expanded to it's "printing" size), take a piece of white printer paper, put it under the nozzle, then land the nozzle. Now grab one edge of the paper with two hands and try to push and pull the paper. If you can easily move it without feeling any resistance from the nozzle, your nozzle tip is too high and needs to be lowered. If the paper is pinched in place and only bunches up when you try to push it, you are too low and need to raise the nozzle. If you can move it but feel a slight resistance** from the nozzle without it actually bunching up, then you're golden.
You will probably need a powered usb hub to connect the drives. Not absolutely necessary but the Pi only has two usb ports (the micro b port is just for power to the Pi) and cannot power notebook drives directly. Plus, the extra ports on a hub will allow you to connect your drives, a mouse, a keyboard, and a Wi-Fi card; all at the same time.
The case I have been using is the [Punnet printable case.] (http://www.raspberrypi.org/archives/1310)
I did not have any heavy card stock to print it on. So I printed the case on regular paper and glued it to some thin cardboard from a box of crackers. To keep the glue from wrinkling the paper, I used a "school glue" style glue stick. You can find glue sticks almost anywhere that sells office or craft supplies. Then I cut it out with scissors and a razor knife.
These glue sticks would be awesome. My kids go through glue sticks like crazy, especially doing crafts for the holidays, lol.
pay attention in class!
elmers is great, six pack dirt cheap (http://www.amazon.com/Elmers-Disappearing-Purple-School-E1560/dp/B00143UIC2/ref=sr_1_2?ie=UTF8&qid=1453149823&sr=8-2&keywords=elmers+stick)
I'm in Australia and use a blue gluestick, but if you're in the US I've seen a lot of queens using the Elmers purple sticks. I buy the smallest size so that it's not much wider than my brow, so less clean up haha. https://www.amazon.com/Elmers-Disappearing-Purple-Washable-0-21-ounce/dp/B00143UIC2
I'm also battling nylon adhesion on a PEI bed. Best lead I've found so far is PLA glue.
Let us know if you get it sticking!
