Lithophane light box

I wanted a lithophane light box that would be powered by a rechargeable power bank,
so I remixed the excellent design by Dumbozo and incorporated a power pack holder.
The rest of the light box is unchanged from the original, It accommodates a 15 cm by 10
cm lithophane with a 60 deg arc

The lithophane is illuminated by two LED light strips, as in the original.
The ones I used can be found here
.
The powerbank I used is a 10400mah power bank and can be found here
.
With a full charge, the powerbank will provide approximately 20 hrs of continuous
illumination.
The lid is unchanged from the original design,
Many thanks to Dumbozo for his excellent work.
