HeartThrob LED Valentine
thingiverse
Thank you, FollowMeOn, for the great [Animated Heart Valentine](https://www.thingiverse.com/thing:679790) design! Since there was plenty of room in the heart box, I decided to add a [microswitch](https://www.amazon.com/Uxcell-a16121600ux1045-Terminals-Momentary-Switch/dp/B06W5XHC9Q), a [CR2032](https://www.amazon.com/Panasonic-CR2032-Lithium-Coin-Battery/dp/B00656235S) battery, and a white LED. When using the outer two switch contacts, it is a normally closed switch that opens when the crank is in the fully down position. The switch fits into the slot on the bottom of the heart box, and the LED slides with a friction fit into the little ring on one of the inner pillars. Through the open hole, the switch can be affixed from the bottom side with a dab of superglue or hot glue. See [zatoichi's make](https://www.thingiverse.com/make:200367) for assembly instructions. Have a different size microswitch you'd like to use with this project? You can [copy and edit this file on Tinkercad](https://www.tinkercad.com/things/3Gdy04DXqED).
