About this 3D model
Here's a simple small 15cm USB powered LED lamp for your desk, or where ever. It's a pretty tough print if you don't have perfect bed leveling :) Print the two covers at .2 or .1mm height. They are just .4mm thick. Stick your lighting in there and you're done. No glue needed it just clicks together. All the source files are here: https://a360.co/2MYXn1s
