Cool, thanks for testing that. I have changed the front plate a little since that version, but only made it a curved edge at the top instead of the 45 angle cut. I also added the option for dove tail joints on the end caps. I think those dove tails will work on those now that I put a 3 small screw driver access slots on the brackets to make it easier to take the end caps off. Seemed like it was going to be difficult to put those end caps with screws and keep the locknuts in place unless they were set into the plastic with a soldering iron. I am going to test print a bracket & end cap today.
