Deluxe Math Spinner

thingiverse

I created pauloblank's Math Spinner Enhanced (fast print, no support) for my family gathering, they checked it out and said "this needs fine-tuning." Many hours of design later I've made a ratcheting math spinner that works perfectly. I reduced the size to save printing time and increased the overall height so you can get more done with fewer pieces. I added additional operators and numbers for solving complex math problems faster. Also, a central core was designed to create a smooth moving mechanism without the hassle of PVC pipes. Now enjoy your fun new math game! Instructions Step 1: Download the files. Step 2: Prepare them for printing by setting normal settings, without support. Step 3: Print out six numbers, one core, one endcap, two operators, and one equals sign part separately. Step 4: Oil the central mechanism so the spinners move smoothly. Step 5: Arrange your six new spinning number components, organize however you like! Step 6: Secure everything using a countersink screw (#6 through #10 should do) attach your endcap onto core. Use a spacer (like a washer) between the core and cap if it gets too tight due to layer stacking adding height. Step 7: Take some time to wear them in before using by starting each one individually rotating them gently until smooth operation starts. Step 8: Finally, start enjoying your newly printed ratcheting math toy with endless hours of math practice!
