This was created for my wife to level out the cover of one of her scrapbooks. After adding pictures, and extending the bars, the binding was too loose. This is for an 8x8 scrapbook with two binding pegs. This scrapbook came from Michaels but it might work with other similar scrapbooks. I printed this in petg becasue that I as trying to use up the rest of a spool, but this should be able to be printed in PLA with no issues. I did set infill to 25% because at the default (15%) it seemed a little hallow and felt like it would crush over time.
