I want to get some material to screw the Neo onto a board. Are the holes 3mm ("M3")? The product I'm looking at is www.tinytronics.nl/shop/Afstandsbusje-M3---6mm-busje---6mm-draad.
Diameter of the holes is 3.17 mm according the 3D PDF. See screenshot. (D=2xR) So 3mm screws fit perfectly. But you have to drill the holes on the mounting plate exactly right, there is not a lot of tolerance here. (+/- 0,1 mm) Or drill the holes a little bit bigger (dia 3.5 mm) BTW: The shop you linked to is top!
