Nice and quick to print fidget toy. it can be used in multiple ways:
There are 2 versions, a rounded one and a chamfered one. For either choice you'll need:
Gently bend the filament pieces to insert them into the holes. They shouldn't require any glue, as the shape of the Backbone will hold them in place. If you feel the filament pieces to be hard to place, you can cut 1mm off and try again.
If you definitely can't get them to fit, I've also added a Through hole version, in which you simply slide a longer filament piece inside, and depending on your printer's tolerance they'll hold by friction or you'll have to glue them.
No supports are required for the Backbone, but supports do help while printing the Top plate
