I've just put up a multiboard over my bench so I wanted to get all my little parts bins off the table. I designed these rails so that you can slot the rear edge of these little bins on and off with ease (just tilt the front up to clear the slot and pull off, do the opposite to stick them back onto the rail). The rails have multiboard snaps on the back for attaching to the board. Print with snaps facing up and supports enabled for build side only, remove supports before snapping to board. Happy organizing!
