Summary

Laser-engraved glass vase, as a steampunk souvenir of Nikola Tesla's Wardenclyffe Tower (look it up, it's pretty interesting).

Instructions

This is raster glass engraving by laser. It was originally drawn to fit Ikea's cheap and cheerful flat-sided tank vases, so you don't even need a rotary adapter. You could put it onto anything though.

Corel and PDF files included.

Original artwork for this is a Blender model by Leo Blanchette

That's a pretty impressive piece of work!
