DupliGator

Behold: DupliGator! This is probably my best Thingiverse posting yet. I'm very excited to share it with you This thing works just like the machine at the hardware store that copies keys, like a router duplicator, and also like a lathe duplicator except that there is no motorized machinery and it works in 3D.

The idea is that you glue a source object to one geared platform using glue stick or other temporary glue, then you adhere a destination object in a removable way to the other gear.
