Grundtal Spacer

I picked up an IKEA Grundtal knife holder at Goodwill. Got it home and promptly dropped one of the spacers from the package. It went bounding off in some non-eculidean direction never to be seen again. But hey, what have I got a 3d printer for? After determining that the spacer was non-ferrous, I grabbed my calipers, opened OpenSCAD, and I'm good to go again.
