Improved Gear Driven Focus Tool for Raspberry Pi Camera v2

This is an update to my original design, with the following changes:

• Cleaned up the geometry of the outer shells.
• Additional post/hole (totalling 3) to join the 2 outer shells
• An opening to see the gears in action

Printing Instructions: 

• Resolution: 0.15
• Supports: No
• Rafts: No

Assembly Instructions: (Best to assemble on a flat surface.)

• Press fit Focus Bit through Gear B as far as it goes.
• Place the above assembly on to Shell A, align the Focus Bit with the hole of Shell A and push it through once more as far as it goes.
• Place Gear A onto the shaft of Shell A, the teeth should mesh nicely with Gear B.
• Press fit Shell B to Shell A using the posts/holes.

How to use: (Two hands are required)

Hand 1: Hold the tool against the PiCam, align the protruding Focus Bit with the Raspberry Pi camera lens.

Hand 2: Rotate Gear A

Optional other use:

Fidget Toy

Cheers.
