Cube 3 Stabilizer

thingiverse

I had a problem with my 3DSystems Cube 3 printer where the print plate would shift during prints. The print plate is held in place by three magnets which are supposed to hold it steady, but it's able to move slightly, throwing off your print job while moving quickly. The solution was extremely simple and won't void your warranty. I 3D printed three rings and used double-sided tape to fix them to the bottom of the print plate. They fit perfectly over the magnets with no play and are not a tight fit. Since doing this, I get perfect prints even on tall objects. There are many different double-sided tapes you can use, but the one I used (in the picture) sticks very well and won't come off when washing the glue from the plate. I used PLA plastic, so if you use ABS, you may get different results. Once you print the three rings, test fit them on the magnets to make sure they fit perfectly. They should slide over easily but not be snug. You should be able to pull them off with no resistance. If they have any play in them (too big), you'll have to adjust the size and reprint them. I included the OpenSCAD file to make it easier. If they are too snug (too small), you can sand down the inside a little. I used a Dremel to get a perfect fit, so use it on the slowest speed or the friction will melt the plastic. If you print this on something other than the Cube 3, you'll probably have different results. Once you're satisfied with the size, apply double-sided tape to the bottom of the rings and cut away the tape from the middle and outside using an exacto knife. Make sure not to leave any in the middle so it won't stick to the magnets. Then place the rings over the magnets with the tape side up. Push them down low enough so the tape will not stick to the print plate when placing it on. Put the print plate in place and make sure it is straight. It doesn't matter how straight it is, just that it doesn't move. But I'm OCD, so... Once the print plate is exactly where you want it, reach under and push the rings up onto the print plate. Remove the print plate and push on the rings to make sure they are securely stuck on. That's it! The print plate should go on and come off easily, with no shifting during printing.
