First Prototype. Test run with only two pieces to see how they are cut and to determine any changes that are necessary to the design. Two problems were encountered, one being that none of the test pieces cut in the earlier post fit into the slots here, an issue which may be attributed to not screwing the MDF down in enough places, and requires further testing to resolve. The other problem is that the end pieces slide in and out rather easily, and can be fixed by redrawing the piece with no end notches, just a uniform set of slots across the entire board.
