Phenakistiscope with Geneva Mechanism

3D printed Phenakistiscope / Zoopraxiscope. This has been designed to be used with an electric drill of some description in order to rotate it fast enough to create seamless movement. It uses a Geneva Mechanism in order to create the intermittent motion; traditional devices used a different means to create the effect of distinct frames, but I personally prefer the use of such an elegant mechanism.

Print one of each part, with the exception of 8_E_clip, of which you will need 5. You'll also need 3x M4x12mm screws, and 2x M4 nuts (you can use 1 M4x8mm instead if you want). The assembly is straight forward; watch the video if you need help.

You will likely need to re-orient the parts (the STL orientation comes from exporting straight from Fusion 360). Most parts can be printed in whatever way is easiest (only 1_Rotor requires support in all orientations, so I recommend printing upside down).

The only one of note is 9_Handle: make sure to print it length-ways (flat on the long edge with the holes perpendicular to the print surface). This makes the part stronger in that direction, and so makes it less likely for the handle to snap off in use. The forces of this mechanism aren't extreme, but if you try to size the disc up, you will find it oscillates a lot more!
