Adjustable Fence Board Gapper

Designed this to help me layout the boards on my fence. Since the posts are not all exactly the same distance apart I made a spread sheet to do the calculations for an "open box" layout as shown in the Fence Boards 8.pdf file.

You can place supports where ever you like, but you will probably end up filing or sanding somewhere to get a smooth action and fit. Each printer and material will have its own quirks.

You will need 2 M4 x 16 or longer bolts and nuts for the thumb screws.
