I'm a beta tester for Gdeal and let me clear up a few things. Gdeal doesn't make or sell anything, but graciously gives his time to design and upload those designs to Shapeways and Sculpteo 3D Printing companies for the benefit of the vaping community. There are others that use the 3D Printing services and sell kits with parts and completed mods. But anyone can order the nylon prints from the 3D Printing services and source the parts themselves if they want to, he has posted online documentation with parts list and source information. The down side to sourcing it yourself is that some of the hardware is only available in large minimum quantites. And yes, the mechanical was named Peko by Gdeal not the DNA version.
