I love this fidget ring but found I wanted a softer outer part of it to make it easier to grip and more satisfying to play with so I remixed it to have a TPU part to slide onto the outer part of it.
Print the parts labelled PLA out of PLA and those marked TPU as TPU - I can't see a way to have different materials per plate in Bambu slicer so you will need to select the right filament yourself.
I have 3 sizes in there - the original has a lot more - so if there is a particular size you want let me know and I will get it added.
