Interlocking Block Sketchbook Cover
thingiverse
Replacement cover for wirebound 5.5" x 8.5" sketchbook. I'll link the sketchbook I got but it could work for any brand that is the same size and bound the same way. The interlocking building blocks that shall not be named stay on pretty well but I'm not sure if it was because of overextrusion. Strathmore 412-5 400 Series 5.5"x8.5": http://a.co/3USPQj0 Edit 9/30/19: Took out all mention of a certain interlocking building block company.
