You know 3d printing is hitting the mainstream when:
- you can 3d print your own water pipe
- there is a site dedicated to 3d printed sex toys with free downloads (aka Dildoverse)
- the 3d printed gun comes up almost daily in conversation
- you regularly get asked if you can print any of the above for someone but soon Staples can do it for them
Cue Fonzi and the shark?
