Initially when I was changing my design I just wanted to redo the holder to only holder 4 frames as that would decrease the time on the printer. I kind of wish I went ahead and did that because messing with the glue was a nostalgic feeling that I did not miss. However, creating the cutouts and the frame allowed me to learn more about the Fusion software and thinking about assembling things in 3d. 

If I had to do it over again, I would definitely use wood instead of acrylic. Wood bonds much easier and would have looked much nicer with the 3d gray than the yellow acrylic. I would also keep my design of 8 shelves, and just make the design thinner and taller.
