Parametric Flashlight Diffuser

This module produces a diffuser cap for flashlights so they can be used for ambient lighting.

For obvious reasons, this works best with translucent filaments (I've been using MatterHackers' Clear Translucent Pro PLA).

Instructions

Print test parts to dial in the proper diameter:

1. Measure the widest point at the top of your flashlight.
2. Set the diameter property to this value plus .5-1mm to
   account for thermal shrinkage.
3. Set the diffuser_type to None.
4. Set any additional configuration properties that you want.
5. Print your part and test the fit of the slip-on ring.

Repeat until the slip-on ring fits. Once you have a good fit for the ring, set the diffuser_type value back to Dome and print your final product with as little infill as you can get away with (0-10% seems to work fine, depending on the diameter).
