Wooden Plank Pattern (Roller)

Black Magic craft does some great things with foamboard, and I've been trying to make a woodgrain roller for a little while now. But I was never happy with the results. So this is the first draft to carve the groove lines and nails holes for the wooden board and then finish the crafting with a wirebrush, like out of BMC video ( See https://www.youtube.com/watch?v=DY3VRBDaXE8 ) NB: This is currently untested. 23/2/19: Uploaded the correct file.
