Handheld Lightup Christmas Wreath

A fresh spin on a classic design can be found here: https://www.thingiverse.com/thing:13179. The plan is to add a sturdy flat base to the ornament. On top of that foundation, a conductive battery holder and conductive path are printed using this filament: https://www.amazon.com/Proto-pasta-CDP11705-Composite-Conductive-1-75/dp/B00X8BQYVM?ref_=fsclp_pl_dp_1. An LED is placed on top, and its leads are inserted through the hole and fused into conductive pads. No LED bias resistor is necessary since the resistivity of the conductive PLA provides sufficient resistance. To create this ornament: 1) Choose a color, initiate the print (no rafts or supports required) 2) Monitor the progress until the backside of the print is complete, then pause the printer and switch to the conductive PLA 3) Once the print is finished, insert the LED into the tree and guide its leads through the holes 4) Bend the leads and melt them into the conductive PLA using a soldering iron; ensure the LED's polarity is correct or it won't illuminate 5) Press the switch to activate the lights!
