iPhone 4/4S bicycle mount. This is a simple and clean design.
You have to print 5 parts in ABS or PLA.
No support or raft needed!
1 part: ONE iPhone case
2 part: TWO mounts
3 part: TWO M3 thumb nuts
You will also need two M3 screws and two nuts. And a bicycle ofcourse ... I have include a Makerware .thing file that contains everything.
You have to GLUE the two mounts to the back of the case by using superglue and let the glue dry for at least 24 hours!
