v-slot extrusion joiner

This is a 20x20 v slot extrusions joiner to join 2 pieces tightly together. Since i couldn't find a joiner for 20x20 extrusions i made my own. Can be used with 20x40 extrusions. I exported 2 versions ,v-slot-joiner-long which is 5cm in length and v-slot-joiner-short which is 2cm in length. Usage depends on your use case. Use at least one joiner at each end. Its a tight fit so you might need to push the joiner in using tools (i used another extrusion ,and a table). if you need any other length you scale the z-axis of the STLs in the slices or you can edit the .scad file by just modifying the length variable on the top then exporting the desired length as STL. As for print orientation ,the orientation used (in my opinion) is the best since it uses no supports and the base can be printed properly while making sure that the middle beam is not printed horizontally (since layer lines can be a weak point). feel free to edit the model to fit your needs.
