Depending on your slicer, printer, printer settings and the colors you chose, more or less trimming, filing, drilling and/or sanding may be required to successfully recreate this model. all parts as necessary for smooth movement of moving surfaces, and tight fit for non moving surfaces. However, prior to assembly, I still test fitted and trimmed, filed, drilled, sanded, etc. I 3D printed all parts using the Ultimaker Cura 4.8.0 'Engineering Profile' on my Ultimaker S5s, which provides a highly accurate tolerance requiring minimal if any trimming, filing, drilling or sanding. This mechanism is a high precision print and assembly using at times very small precision 3D printed parts in confined spaces with highly precise alignment. I 3D printed 2 'Bolt, Plate.stl', 15 'Spacer.stl' and one each of the remaining parts. One 36' length of 2mm diameter music wire.Sixteen flange bearings (F6700ZZ 10 x 15 x 4mm flange bearing).The only contact between each slice must be the pins in the slots, thus careful 3D printing (no warping) and assembly (bearings completely flush with the bottom of each slice) are required to successfully 3D print and assemble this model.Īs usual I probably forgot a file or two or who knows what else, so if you have any questions, please do not hesitate to comment as I do make plenty of mistakes.ĭesigned using Autodesk Fusion 360, sliced using Ultimaker Cura 4.8.0, and 3D printed in PLA on Ultimaker S5s. This process continues down the slices until the top rotates 180 degrees at which point the bottom begins to rotate to put the heart back together. When the top turns 10 degrees, its slot comes in contact with the pin in the slice below and that slice begins to rotate, and when the slice below rotates 10 degrees, the pin in the slice below it begins to rotate. Each pin fits into the slot in the slice above it, and each slot is 10 degrees in arc length. To rotate the inner slices (between the top and bottom) the bottom and inner slices contain small metal pins and the inner and top slices contain slots.

The motor and gear system is designed to rotate the top slice 180 degrees while holding the bottom slice stationary, then hold the top slice stationary while rotating the bottom slice 180 degrees. This animated twisting heart is constructed from eighteen heart slices. A Valentine Heart for my Valentine, with a twist!
