This is a fidget spinner using the house shields from Hogwarts School Witchcraft and Wizardry!
The original shields are not my design they are from this talented artist shadowbuilder available here. https://www.thingiverse.com/thing:2131600
The M10 nuts were just too tight so changed the tolerances to allow better fitment.
Freeze the Nuts and Bearing
To get the nuts and bearing in freeze them so they shrink a touch :)
