Phonecone iPhone4 version
by eagleapex, published
I saw this design: http://arkwhat.com/17-arkcanary-ii and decided to make my own. The holder.stl fits an iPhone 4 ass, but the parts are separate if you would like to make one to fit your phone's ass.
Video if it in action: http://www.youtube.com/watch?v=apK3GMyn45w
Designed and printed at http://www.hive76.org/
Print both pieces and weld together with Weldon 3.
I found it helpful to use 2 clamps. Clamp the holder to the table and then the cone on top.
