Having finished the build and printed the test piece and a simple design I thought I would use up the spare M4 screws and nuts. I had assumed as I didn't have any printed parts left that the side panels fitted outside of the frame, but then found they fit in the frame a little like the base inspection hatch. But although I have plenty of M4 screws that fit the holes the panels fit flush so they will need fittings similar to the inspection hatch ones, not the same as the hatch uses microbarbs. Is this a PIY (Print It Yourself) part of the kit? If so is there a ready made design we can download and print?
