I made a rail to hold some boxes of components I have, so they take up less space than sitting flat on a shelf. The rail is 5mm thick and 8mm wide, so should work to hold most things.
Print with the top of the rail on the bed (as in the picture), supports are needed for the pegboard clip parts, I recommend organic supports as they're easier to move. Depending how well stuff sticks to your bed/avoids warping, you may also need a brim.
The author marked this model as their own original creation.
