Deluxe Math Spinner

thingiverse

The only change I made was shortening the core to fit six rings instead of nine. This is a a ideal version for younger kids. I used a screw to insert from the end cap and it holds in place nicely. Editted the remix from DanielStein's (Original from pauloblank). Printed in PETG on the Bambu X1C. All parts slide on perfectly and the ratchet system works perfectly.
