Floor Levelling Token

I got tired of squinting to see the lines on the ruler when levelling my basement floor before installing hardwood flooring. The top of the middle flat piece is ~11mm which is where my levelling laser hits. the top of the upper curved piece and the bottom of the middle flat pieces are 5mm (3/16th) which is the upper and lower limits at a distance of 10ft that the manufacturer recommends.

Side note: While digitally the little dots on top of the crown portion looked good, in reality at this size they easily snapped off leaving a series of very sharp points.
