Fidget toy mashup of the “Print-in-Place Fidget Ring” by Makkuro, and the “Cute Mini Octopus” by McGybeer.  
 

The inner ring spins, with articulated tentacles attached to the outer ring.

• Updated V3 - Improved fit of inner ring, and flusher connection to tentacles.

Just slice and print.  No supports or brims necessary, just make sure you have good bed adhesion!

Spin the inner ring a few times to work in.
