I couldn't stand just copying Emmett's heart, so I added Cupid's Arrow and a display stand.

The arrow is in both dual-extrusion (because I can) and one-color versions. The two tips and two tails WILL NOT work individually.

If you want just a heart, look at the remixed from. The stand will work with my version of the non-arrow heart as well.

Allow 7-8 hours to print everything at .2mm layer height.

Arrow Through Gear Valentine's Heart With Stand!

I added a hole, arrow & stand to Emmett's heart. If you want a heart without the arrow/holes, check the "remixed from" on this thing's page: http://www.thingiverse.com/thing:670944


No rafts are needed. Support is only needed for the stand.

Print the 2 plates and the center for the heart, I used red, 10% infill, .2mm layer height.

Print the stand if you want it, I used gray, but whatever. 10% infill, .2mm layer height. Probably need to use supports when printing.

Print the arrow, I used 0% infill, .2mm layer height, they have "built-in" supports that should snap off after printing.

  • Dual extruders can use the 4 STL, two for the tip & two for the tail. I made the fins/point red and the shaft gray.
  • Single extruders should print the one-color arrow, you can

Test each bit before snapping in, they'll be really smooth where they join. If not, something's messed up.

A) The center has "small" faces and "big" faces. Start with a "small" face up, put a pin in each face.
B) Snap the V-notched middle of the top of the heart to the top small face.
C) One end of the middle part has a single tooth in the middle (the other side has two teeth around a space), line up that single tooth with one of the big faces, that tooth will be the "right" side of the heart.
D) Find the lobe, which has a hole for the arrow tail.
E) Attach the "lobe" next to that single tooth of the V gear. The hole is closer to the "top" of the lobe, and the top two center teeth should fit nicely over the single tooth of the V bit, we'll call this the right side of the heart.
F) The other gear with a hole has a mirror image, find both of those, they're fairly flat
G) The "hole" gear is on the front left, little teeth toward the lower right, big teeth toward the upper left. Find out where the teeth align nicely with the top V and snap in. It should feel pretty smooth if you got it right.
H) The mirror of the hole gear goes in the back of the V.
I) Find the oval/rounded gear, that goes on the left side, the bottom side should have a single centered tooth. This gear should fit smoothly between the two previous gears.
J) The bottom bit is next, it is the pointy gear. I think it's symetrical. The longer side aligns with the heart.
K) The last two gears are the smallest round gears. The smallest teeth go towards the center of the heart. If you can't make them fit, they're probably backwards.

Add Arrow:

The arrow should slide into the holes and would form an imaginary straight line. It doesn't really matter which end is which. You may need a dab of glue to keep it snug


The stand is amost tricky. Clean off the supports, then it fits between the gears in the back of the heart. You may have to wiggle the gears a bit. The stand blocks the gears, so you'll have to take it off the stand to play with it.
