Heart gears supersized - pump up the volume 600% baby!

Emmett's Heart Gears scaled linearly by 180% for maximum loving. The largest part is 12x12x7.5cm. The layout was tweaked and I pushed some polygons for slightly better slicing.



Because of a known bug in Slic3r, we recommend Skeinforge for this model.


For smooth transitions over the curves, try 3x perimeters, 4x solid layers and drop your infill to a cheeky 10% to save material. Our print weighed in at 0.6kg. Print the connecting pins as normal and use Multiply to get the number required (4x short, 4x long).


Print in gorgeous Cherry Blossom Pink PLA :)

There are some pretty bold overhangs, so try a desk fan lightly blowing across your build to avoid curling edges. Minimize warp by printing on Kapton and increase your heated bed by 5-10C.


Gears 2 and 4 are mirrored but not quite identical, so test them for fit (without pins) to check what side they go on (front or back of the heart). The same is true for Gears 5 and 7. We have shared our assembly sequence on Flickr: http://www.flickr.com/photos/faberdashery/

Congrats, your model made it on my top 3D Printed Valentines Day Gifts! See here for the article: http://3dprintingninja.blogspot.com/2015/02/top-5-free-3d-printed-gifts-for.html

I love this........ and really sad that it has the slicer glitch. As I have worked for moths fine tuning my printer with slicer. Currently trying to setup the config file. Is there a patched version of piece 5-7 out there anywhere?

Love this! I must get pink before printing!

Have a few red sharpies? Get the filament colorizer and with white filament and red sharpies and you'll get pink!

Yep, we went for Cherry Blossom :)

Do you have a link to this color filament? I can't seem to find it. Thanks!

I found that the pins aren't that hard to fit in as long as you squeeze them a few times before you try to fit them in. Just reach for a pair of pliers, or even just bite down quickly.

This is, by far, the best print I've made yet. Absolutely nothing broke and all the gears fit together perfectly. Kudos.

I like. Except it is almost impossible to fit pins with 100% fill..

What type of printer did you print this on?

RepRap (Prusa) Mendel.

very interesting.

how long it take to make, what is the cost of the material?

It consumed about
£15 of plastic and took a few evenings to print.

What is that in plastic weight about? Also is that solid?

Very nice! This scaled up version is a real eye catcher and would be a lovely gift :)

We'll see how big these things can get when my replicator gets here! :)

WoW! that's nice, you'll have to make a little (big) stand for it.

Yes, please design a stand for the big heart! Nothing complicated or too big to take away from the heart, itself!

What to do with unlimited printing filament supply....Make huge things! :)

I want your filament now... :-$

Nice print, and thanks for sharing the detailed printing directions.
