Transforming Bean to Heart Locket, it does what it says on the tin, and that's with a twist transform's from a bean to a heart shape, this locket was designed in Fusion 360 and printed with the BambuLab X1 Carbon in 12mins, works with Magnets and has a satisfying click when rotated.

Its best to offset the centre axis, these magnets are 3 per side achieving a stronger pull, where the rotating side magnets are 1 per hole = 4 magnets in total, magnets are 5 x 2 mm Neodymium tight push fit.

I had some suitable necklace chain to hand and a lobster claw clasp. the ring on the bean is the small screw in type eye.

Was harder to design than I had imagined but got there in the end.

Thanks for looking.
