6/23/2021 UPDATE: Redid the interlocking uprights into three pieces to make the shelving unit more modular.
When I came across Ratm3at's Mini Shelving, and the remix by and_kres, I knew it would be perfect for displaying my collection of playing card decks. Unfortunately, the dimensions weren't what I needed. I needed a height of 12in (30.5cm) and a width of just over 6in (15.5cm), but this wouldn't fit on my Prusa Mini's 7in print bed.
- I resized the shelves, making a version for one deck per shelf, or two decks per shelf side-by-side. I also tightened the tolerances on the shelf pegs, as they came out too loose on my printer. - I also created a crosspiece (actually just a chopped-down shelf) so the decks don't fall backwards off the shelves. - I resized the uprights, and cut them into two pieces. My initial design used a 3-prong clip ("Upright Joint Vertical") to hold the upper and lower uprights together. This is sturdy enough, but it later occurred to me to just make interlocking teeth in the same style as the shelf attachment, so I've uploaded this version (Stackable Top, Bottom, and Middle) as well.
If you use this for decks, mount the shelves so the raised lip is facing up, and snap the crosspiece into the back row. If instead you're using the shelves for other applications, the crosspieces probably won't be needed, as they aren't structural.
