See files and project at https://git.nexlab.net/nexlab/3dlamp/

base design derived from http://www.thingiverse.com/thing:1634938 , thanks to ddanijell for it.

Difference from the original design:

• removed a layer to adapt the design to 5mm plywood
• fixed size issue on button extensions holes
• added top layers version for 5 or 2mm plexy
• reinforced top buttons
• converted design files to SVG with template for k40 laser machine with inkscape and marlin modification
• added 3d printed rubber feet design

Other than that, the firmware is totaly rewritten from scratch and released under GPL license, other improvements will be done in future.
