Basic yoyo 45mm

This is a very basic concept yo-yo. It is very small and pocketable. I wanted to have a small yo-yo with some heft which felt like those of old. I advise you to print it as dense as possible so that it has enough weight to spin well, but that is up to you to decide.

Requires to have an m4 nut and bolt (20mm or so) and a spintastics technic core (approximate equivalent model provided, also available from Dale Oliver, track him down).

This MAY require to be roughed up in the middle in order to be responsive, and may be better responsive if starburst was added or the gap were made a hair smaller.

Feel free to leave me feedback, and try some modifications of your own, as I am actively testing this print.
