I use this model as a sall portable UV light for varius tasks including curing small spots of UV glue. This modle is compatible with any color 5mm led diode, and a watch battery.

Print + Assembly:

Works fine in PLA with standerd .4mm nozzle, and .2mm layer hight. To assemble insert LED with the longer leg on the side with a large cicular cut-out, then insert the wath battery with the smooth side facing the same cut-out(I recomend puting a small amount of tape on the bottom of the LED's longer leg to keep it from touching the battery until the button is pushed), next instal the bottom cover, and finaly place the button in the circular cut-out ensuring the grove alines with the LED's leg, and atach it carefuly with tape ensuring its not to tight forcing the LED to illuminate without pushing the button.
