Led Light (Crystal on Rock) - USB powered

A led light with crystals placed on a rock. For a more natural look, you can paint the rock. Less light will come through the rock then.

Crystals are hollowed out and in the base there is a cut-out for the led light source and the cable (USB).
Led source is a Micro Usb 5730 Led Panel 5V.
Cut-out is made 40.2x52.36 to adjust for shrinking.
I desoldered the usb connection and soldered a USB cable directly to the board.
For the cable I just took an "old" cable and cut the micro-usb connection side.
The green crystal light is printed with a DLP printer (upside down with supports to allow the liquid to flow away), with translucent green UV resin.
The orange crystal light is printed with a FDM printer, with a fluorescent orange PLA filament.
 

It is advisable to add 3 small adhesive (rubber) feet to the base, so that the led can cool!

I have added the step-file so adjustments can be made for other led sources and/or scaling the model.
