Summary

Sometimes I have to use reels that have very small holes. I took inspiration from several designs to create a holder that could fit a reel with an opening of 30mm but still strong.

Uses typical 608 fidget spinner bearings. Can be printed on the Mini printer with supports. I used simplify3d to print the bottom at about 50% fill then reduced to 30%. I put a drop of hot glue on the pegs to make sure I don't lose any bearings.
