Micro Print-In-Place Bearing Finger Spinner

As seen on MakerWorld: https://makerworld.com/en/models/655563

My take on the famous fidget spinner - easier to hold as you can slip it on 1 finger. No assembly required, it is print-in-place and will work off the bed. Comes in a variety of different sizes which will hopefully cover most fingers:

• 16mm Inner Diameter (Small)
• 18mm Inner Diameter (Medium)
• 20mm Inner Diameter (Large)
• 34mm Inner Diameter (2 Fingers)

All have an optional extra outer ring to give it more weight and spin faster for longer.
