Trying to Design and 3D Print one of these Illusionist Lockets has been a bit of a challenge, they have to be so precise for it to work nice and smooth.

Most diy online models are made out of wood some good, some not so good and I couldn't find a 3D printed version so I thought I'd have a go myself.

Its called the Illusionist Locket because not only does it transform from a bean shape to a heart shape with a twist, but whilst in the heart shape the top 2 slices revolve to reveal photos within(Popped a couple in there of the wife and me as an example)

Its called a locket but it could fit in the pocket quite nicely as a fidget toy

The locket works with magnets and you will need 7 no 5mm Diameter x 2mm Depth and 1 no 5mm Diameter x 8mm long I purchased the magnets from 1st4Magnets UK but they will be available elsewhere, the magnets are a snug push in fit but I secured them with superglue as well, be careful to keep the Super Glue confined to the holes and don't apply too much.

The white version in the photos is the prototype, but gives you an idea.

The centre Axis holes are 6mm deep and when the 8mm magnet is secured it leaves 2mm protruding for the Axis, apply glue to the opposing 6mm hole and place one of the 5 x 2 magnets on the end of the 8mm magnet and push it into position, this now forms the pull to hold the 2 main bodies together and the revolving Axis.

Then used the same polarities for the top of the main bodies, then did the same with the 2 thin slices, being honest there is a bit of tweaking required to make these work correctly on the revolving parts, but worthwhile when you get a result.

Care has to be taken when fitting the magnets, getting the polarities correct is Paramount ,

On the original lockets there is a motif, I wasn't sure what to do with that to be honest so I just left it blank.

Get it right and you get those satisfying clicks from the magnets when going through the motions.

Tough project from a design point of view but we got there in the end.

When Printing, ensure you have a clean build plate, I printed from the face sides down as in the print preview, but they could be printed side up.

Would make the perfect gift for a Christmas/Birthday or New Year.

Thanks for Looking.
