UFO Spinner!

Probing New Frontiers in Spinning Technology! Did you receive your Alien3D UFO Box yet? Have you got 25 pennies on hand? I know you have those two bearings somewhere! Then all you need to do is download these files and GET PRINTING! This spinner can be printed with or without the pennies. However, to really make this "fly," add a pause to your G-code to allow you place 25 pennies inside your saucer to give it some serious weight! Assembly is easy! Clearances are tight, however, so you will want to print on a printer that is well calibrated and some gentle persuasion may be needed to get all the parts together. Rest assured, it CAN be done and the results are fun. ONE WEIRD TRICK for better spinning! ------------------------------------------------------ If your bearings are lubricated with grease, that can slow down the spinning action. Before installing your bearings, test them - if they don't spin for more than a second, try this for a better spin: 1. Remove any shields from the sides of the bearing if they exist. You should see the ball bearings and bearing cage exposed once you do this. Do not remove the ball cage. 2. Fill a shot glass or similar small glass container with isopropyl alcohol. 3. Soak the bearings in the alcohol overnight 4. Remove the bearings from the isopropyl alcohol and allow to completely dry on a paper towel 5. Add a small amount of light machine oil to each bearing Following this process, you will likely find your bearing will spin considerably better. I have made spinners with inexpensive bearings spin for 2 minutes or more! Let's see what YOU can do! All Alien recruits, report for duty! **Please note: this toy does not literally fly. However, it can spin very, very well if you do it right.** If you want to support me and get GREAT filament at the same time, please visit Proto-Pasta using my affiliate link and get yourself some excellent HTPLA!
