About this print
A multi-part mechanical sculpture shaped like a heart, made up of interlocking rotating gears that assemble without screws or bolts. The design is a decorative geometric object, often given as a gift around Valentine's Day, and demonstrates how gears can be integrated into an organic form. PLA is a common choice for this type of display piece, as it prints cleanly at the detail levels the gear teeth and heart profile require.

UPDATE: There is a new version of this design which is more reliable to print and easier to assemble. I highly recommend you use it instead: http://www.thingiverse.com/thing:243278

At last, here is the much-requested 100% printable heart gears. No more ugly bolt holes! This was designed along the same lines as the screwless cube gears: http://www.thingiverse.com/thing:10483, and in fact uses the exact same center block (though the pins are slightly shorter).
UPDATE: If you lack a 3D printer, you can now buy these from CarryTheWhat at http://www.etsy.com/shop/CarryTheWhat.
The size has been increased a bit from the previous version to accommodate the printed pins, so it now measures 100mm across when assembled. Since everything is now printable, it should be easy to scale this design up or down as you see fit. At this size it took me ~6 hours of printing time on my TOM.
Formatting may have been simplified. These are the independent maker's instructions and fitment claims; Hark Tech has not independently verified them.
Printing Screwless Heart Gears
For Screwless Heart Gears we would normally reach for PETG — it is tougher and more heat-resistant than PLA, ideal for parts that take load or live somewhere warm. We set the layer height, wall count, infill and supports to suit the model and how you will use it, and those choices are already priced into your instant quote. Want a specific colour or material? Tell us and we will match it where we can.
