Rising Dovetail Joint

thingiverse

This is a demonstration piece useful for studying and understanding the geometry behind the rising dovetail joint. It can also serve as a fidget for someone who enjoys woodworking projects. The two parts slide together to create what appears to be an impossible wood joint. A 0.01" (0.25mm) tolerance gap was included in the .STL file to allow for an easy fit straight off the printer without much, if any, post-print filing. Also included is the OpenSCAD version, which allows for the male part with the tongue to be generated, the female part with the tongue cut out to be generated, and the ability to adjust the tolerance gap on both so the fit is easier straight off the printer. Use the Customizer to make this Rising Dovetail exactly the shape you want! Check it out. Note: The preview for the female part looks a little weird, but exports to STL just fine. I'm trying to figure out a solution. Any suggestions? Updated (3/4/17) - The Customizer OpenSCAD file has been updated to include an option to create the male or female part and preview both together. However, do not export the both option! I'm still working on making the tolerance gap function work. (The option in the Customizer doesn't do anything yet.) I'm also trying to resolve the weirdness in the preview of the female joint and both in the Customizer. The part looks fine when the STL file is created. I assume that I need to extrude the negative of the tongue part slightly past the block. Any suggestions? To be continued... Updated (3/9/17) - Tolerance gap added! Half of the tolerance was shaved off from the male part and half from the female part. My next thinking is about trying to make the tongue and the tongue cutout into modules so they can be placed in other locations or multiple locations. Updated 3/17/17 - Much of the code has been converted to use modules, simplifying the code and allowing for the possibility of adding future Customizer options. I'm thinking about adding the capability of including multiple joints on a single part...
