No supports required, this shelf holds up to 5 cutting boards with a maximum thickness of 17mm. The two pieces slide and fit snugly together using a dovetail style joint, with glue needed to create a secure bond, and 4 screws to mount to the wall. Holds 5 wooden boards very well, with no visible deformation or strain to the product.
I had mine printed in Prusament PLA Black on my MK4 at 20% Infill (Cubic)

Attached is a PDF showing the screw hole placement so you can mark the correct distance onto the wall before drilling.
