30+ Min Fidget Spinner

I'm usually a spinning-top person but I came across the 25 minute Guinness World Record for spinning a fidget spinner and one finger and figured I should give it a shot :)

A few weeks and prototypes later, I made this 'Pulsar' Fidget Spinner (named after super-dense spinning collapsed stars). It has a massive Tungsten flywheel, measures 70mm in diameter and weighs over 400g. The core and buttons are custom anodised aluminium parts made by JLCCNC. The bearing used for the record was a 'Go-Fast' hybrid R188 from unquiet hands.

I made a video about the project which is on my YouTube channel here: https://youtu.be/DhhtLpS9UTg?si=US03lpY60SPGZYLm

I'm definitely interested in making more designs in the future, and I'm very happy with the parts from JLCCNC - everything fit together on the first try! This is their website: https://jlccnc.com/

If you have any feedback do share :)

Flywheel x1: 70mm OD, 50mm ID, 14mm height (I used tungsten, any dense material works)

Core x1: CNC file attached (I used aluminium, any light material works)

Aluminium Button x2: CNC file attached (used aluminium, any material works)

Bearing x1: Any R188 bearing (I used Go-Fast hybrid ceramic by Unquiet Hands)

CNC machine 2x Buttons and 1x Core. I used JLCCNC's service and was very satisfied.

1) Press-fit the Core into the Flywheel

2) Press-fit the Bearing into the Core

3) Screw an M5 Grub screw into one of the Buttons

4) Screw the Buttons together from either side of the Spinner

5) Finished!
