This is a quick little set of modules that I made in openscad to quickly generate dovetails to join two objects together.Hopefully these will be useful to someone...The included STL file is just a sample of the output.There are 3 relevant modules:male_dovetail(max_width=11, min_width=5, depth=5, height=30, cutout_width=5, cutout_depth=3.5) This produces a male dovetail with the dimensions specified. The cutout_width and depth specify the dimensions of a cutout in the center of the dovetail that will hopefully provide some spring or flex to allow them to go together tightly.female_dovetail((max_width=11, min_width=5, depth=5, height=30, block_width=15, block_depth=9, clearance=0.25) This produces a block of the specified dimensions with a dovetail cut out of it with an added clearance on three sides.female_dovetail_negative(max_width=11, min_width=5, depth=5, height=30, clearance=0.25) This produces the negative of the above module so that you can subtract it from an object.
