Fidget Spinner - One-Piece-Print / No Bearings Required!

thingiverse

Fidget Spinners are a popular toy enjoyed by people all around the world. This design provides the same ability to 'fidget' as any other Fidget Spinner, but it is a one-piece-print that requires no metal bearings. It should be almost ready to spin straight off the build plate! The design features four designed-in bearings. With a well-sliced file printed on an accurate and precise machine, the bearings should be free or take very little effort to break free straight off the build plate. As soon as the bearings have been freed, add a small amount of lubricant to the moving bearing surfaces (refer images) and you're in business - ready to give your Fidget Spinner a good spin. It might not be as good as a spinner with metal bearings, but it should still spin very well and is definitely fun to fidget with! You can spin your Fidget Spinner in several ways - a smooth-running spinner can be spun by holding it in the center then flicking one of the arms from the top or bottom. Or you can get a faster spin by hitting one of the arms with a finger on your other hand. As there are four bearings designed-in, you can also hold one of the outer bearings and flick the spinner around using them instead of the centre bearing (refer images). TIP: Once all four bearings have been freed, apply a good spray of silicone lubricant into the grooves between the main body and bearing on both sides of the spinner. Silicone is an amazing lubricant that makes 3D printed surfaces move really well against each other. This has been test-printed numerous times to ensure the expected function can be easily achieved with minimal effort - and you don't need to buy any metal bearings! Will a spinner with metal bearings spin better or longer? Probably, due to the added weight, but this does a pretty good job at much lower cost and it's entirely 3D printed. Have fun spinning your Fidget Spinner, and please post images of your creations for others to see. Please refer to the print settings/instructions and images for additional information.
