The Stubby Mini was made because I wanted interchangeability with the rings I printed, however on my Rep 2, one you put a ring-a-thing on, it STAYS on.
This smaller version allows the ring to stay on tight, but still pop off with some force.
Use a raft, it makes life easier when printing all ring sizes at once. TRUST.
