The cheapest acrylic sheet in my local hardware store is 8" x 10", so I wanted to make the most of the surface area by increasing the height of the tower. The new dimensions for the acrylic/polycarbonate sheet are 7 ½" x 4 ½". I had my sheet cut to 7 ¼" in length but found it is slightly too short for the model I remixed, so 7 ½" should be a better fit.

Print 20 pegs in PETG. PLA pegs broke after repeated use in my testing. XY size compensation may be needed if the peg does not snugly fit. I recommend using hot glue to mount the pegs to allow for them to be removed if necessary, though superglue can be used instead at the expense of the inability to replace pegs easily.
