Found perfect fitting baseboard for the A3 Emblaser at Bunnings today. Basically is a white chipboard shelf $11
Shelf Pack Suits Bedford Furniture Tall 1 Door Unit (600mm)
I just fixed it to the Aluminium base with some double sided tape and ran the 10x10 Grid from here http://forum.darklylabs.com/index.php?p=/discussion/128/useful-cutting-engraving-files#latest
, as the shelf is white the contrast on it is fantastic and really stands out.
