Summary

This is a Keychain version of Emmett's screwless heart gears!

I'm still working on getting the scale right (small enough for a keychain, but big enough to print the details)

As it is, It needs a rather large fan blowing across the print to keep the gears from getting mangled.

Current scaling = .5

All parts are the same except Gear8, which has a hole through the tip for a keyring.

Instructions

Preliminary instructions:
1) Choose where you want the hole
If you want it on the top, print a regular heartgear8, and gear1forkeychain, otherwise do the opposite.
2) Print all the other gears, and the core: BEWARE, THESE ARE VERY CHALLENGING PRINTS! You may need a cooling fan blowing gently on the print, but you have to make sure it doesn't cool the platform too much and pop the print off!
3) print one of each of the pin parts, test fit them, one will fit snugly, and allow the gears to rotate, the other won't, depending on the calibration of your printer.
4) Print the rest of the pins (and probably a few extras)
5) Assemble all the parts
6) Impress your special someone on valentines day with an awesome heart keychain/pendant!

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

Can you put all the pieces in one file to print at once? Some of the screwless cube files do all the internal components in one file and all the external components in another... thanks.

any updates on this? I like the keychain connection on this better than the other one i found (the hoop rather than straight in the heart itself)

Hello, i was just wondering did you go to burning man last summer?

Any update on this? I would like to help you get this corrected.

Do you have the original center or are we working from emmetts?

Once I perfect my new pin design, yes i would, but at the moment, it can't move...

I printed one - but I can't get the pins to work well - the center of the body seems a little too large - the gears didn't come out too badly. Need to tweak those a bit and see what I can do with them.

I'm almost wondering if something this small might lend itself better to a small machine screw to hold it into the center.

Any luck? I agree, the screw idea sounds probably the best idea for something this size (especially if you want it to last the wear and tear)

I just uploaded all the rest of the gears, plus an alternate attachment point (Gear1) so that the heart can hang upright! Enjoy!

You need to upload the STL or SCAD.

I hope you share your modifications once you get it done. I can run the Gcode - but my printer is likely calibrated differently than yours. It's a great Idea!

ack! sorry! Uploaded the wrong file!!
