## Objet swab texture testing
first objet test for "hair" or swab texture. Pillars .004" in diameter, .01" tall with .0025" spacing between them.
not in the right ballpark, texture is barely detectable.

Amira's tool for generating patterns is great but I quickly went out of the value range with the XY size, as well as the feature size of the pillars. I'm still throttled by cad performance, and have dropped grids from 70x70 to 35x35 to relieve that
I was able to obtain the file Formlabs is using to produce swabs. I printed one and attempted to measure the features.

This gave me some reference and today before leaving the lab i started an array of pillars .02" diameter, .03" tall with .015" spacing between.
