I wanted to get an under shelf Benchy display but couldn't find the perfect one because I wanted to use screws behind the shelf. Decided to go with this great Benchy Shelf. Just whipped together this clip that holds the mount snug without being visible.

Thicker portion is 10mm x 10mm x 3mm.
Screw hole is countersunk and perfect fit for a #4 wood screw.
Thinner portion is 10mm x 5mm x 1.5mm.
Perfect fit to hold down a 1.5mm thick piece of plastic.
