16mm vial rack for Elfa Utility Board

thingiverse

This rack supports 19 vials or test tubes featuring a 16mm outside diameter and attaches securely to the Container Store's Elfa Utility Board, a pegboard alternative.\r\n\r\nIt shouldn't be challenging to replace the Elfa hooks with your preferred hook or fastener hole if you're using a different type of board for hanging. I utilize mine for storing ink samples from Goulet Pens.
