SPINNING TOP (1/4-20 NUTS)

thingiverse

My kid loves his favorite spinning top, so I decided to create one that spins well for an extended period. This project requires twelve 1/4-20 nuts. To ensure everything stays in place, I used superglue to bond all the pieces together securely. This prevents them from falling out and the top from malfunctioning. To print the body of this spinning top, simply place it upside down on your printer's build plate. A small detail worth noting is that the handle features a 0.2mm thick by one-inch diameter brim, which you'll need to remove after printing. If you're using Inventor, be aware that it often saves models with an incorrect orientation. As a result, you might have to rotate the model to achieve the correct alignment. UPDATE October 1st, 2019: After experimenting with a 1/4 inch screwdriver bit for the handle, I found it to be too heavy and caused the top to wobble excessively. To resolve this issue, I designed a printable handle that is significantly lighter and should perform better.
