This design is for a cubical 3-D maze that you roll a small steel ball through. Drop it in the top twist the cube this way and that, and get it to roll out the bottom.
It is made to cut from a 0.093” thick 11” x 14” sheet of acrylic sold at, e.g., Home Depot. Sheet thickness varies a bit from batch to batch, but this design has worked well with all the batches I’ve used.
