Priit Laes 9b364e410c Use proper radius value for r_fo3
The same value used in baseplate is now handled as radius (instead of
diameter).

This setting allows 'slimmer' tabs for use with thinner labels, so smaller/narrower bins can be labeled and still keep a reasonable opening at the top. NOTE: The measurement is not 1:1 in mm, so a '3.5' value does not guarantee a tab that fits 3.5mm label tape. Use the 'measure' tool after rendering to check the distance between faces to guarantee it fits your needs.
