I thought it'd be interesting to CAD and print a bed, so here you go! This is a queen bed like I might picture as a kid.

For printer settings, be wary that the hole in the backboard has a longer overhang than I had anticipated, and depending on the material and printer settings you might have trouble there.

Also, the burnt plastic in the middle of the bed in the actual picture is not part of the design, you can thank my leaky hot end for that.
