Darkroom Test Strip Maker v2

This is the improved version of my test strip maker. It allows you to print a 4x5" test strip using the same area of the negative for each of 5 1-inch test exposures, by pushing the paper through the device instead of uncovering parts of the paper as you go. Simply stick down the base and exit cover to your easel (it will stick using magnets if your easel is ferrous), insert a 4x5 sheet of paper, and alternate exposing and advancing the paper in 1" increments using the provided stepped pusher tool.

Also optimized this for printing at 0.2 layer height instead of 0.24, as print times are no longer much of a concern. A normal 0.4mm nozzle should work fine, although larger ones would probably be fine as well.
