Basically, I got tired of pulling my dresser out to grab whatever my cats decided to shove down that day. Not really parametric but should be relatively easy to edit to your needs. Sized for a 66" dresser.

Printed on a Bambu Lab A1 Mini. Size up or down to your needs, f3d files provided. Files have pretty tight tolerances, about 0.1mm total. STLs are uploaded in recommended print orientation. Might do a slight redesign so it doesn't require supports, but for now this works for me, was a quick project just to solve a personal frustration. 

I designed this specifically so I could print it in 10 pieces to go behind my dresser (167.64mm each, 1676.4mm/66 inches total). I also wanted it to fit on my printer. There's one to allow for a cord to pass through, specifically for my A1 as it sits on my dresser. 

Printed with 0.6 nozzle, black PETG @ 0.24mm height, personally don't care if layer lines are visible as the lights in my room tend to be pretty low.
