Meticulously chosen products!
Fidget Spinners are a popular toy all around the world this design provides the same ability to 'fidget' as any other 'Fidget spinner' however it is a one-piece-print with no metal bearings required. It should be almost ready to spin straight off the build plate!
TIP: Once all four bearings have been freed apply a good spray of silicon spray or other light lubricant into the grooves between the main body and bearing on both sides of the spinner. Silicone is an amazing lubricant and a simple way to make 3D printed surfaces move really well against each other.
This is an easy print of a fun gadget but does require an accurate / precise slicing app and machine to achieve the necessary clearance between the moving parts so it will spin well and freely. Applying the lubricant is also essential to getting a really good spin and being able to spin it with just one hand (Metal bearings require lubrication too so this just requires the same).
Retaining the standard scale is recommended to maintain the designed in clearances and also ensure sufficient space between your thumb and forefinger for it to spin. However, you can get creative with colours by pausing your machine multiple times mid-print and changing filament... print in your favourite color or color combination to make your own unique 'Fidget Spinner'.
Everyone needs their own 'Fidget Spinner' and they make great gifts as well... and with this design you don't need to buy any expensive metal bearings to achieve a similar result. 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!
Higher than usual shells and infill is recommended as this adds weight which will help your spinner maintain momentum

Clean up, spray with silicone lubricant then give it a spin...
This 'Fidget Spinner' will print well when printed from a well sliced file on an accurate / precise machine. The printed-in bearings will need to be broken free by wriggling them or, if necessary adding a fraction more force (...but being as gentle as possible) with a craft knife to clear away any visible excess filament. With a good slicing app and well set up machine the bearings should be able to be broken free by hand (i.e. no tools required).
Once all four bearings have been freed apply a good spray of silicon spray lubricant into the grooves between the main body and bearing on both sides of the spinner. Silicone is an amazing lubricant and a simple way to make 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!
