This is themed after a Cork Art Diorama. I printed the cork part at 30% sparse infill with supports to make sure all the little parts printed well. The holder was printed at 5% sparse infill. I did put a little lip on the back of this holder to make sure it does not fall through backside. Apply super glue as needed. There was a little under extrusion on the back side from the supports, but turned out pretty well. Enjoy!
