Definitely, edging those cubes is N^3 more work than drilling a few k holes in a board 😱
Good on your test dummy to give the nod for "real" wood versus the termite leavings, but certainly good that you got the prototypes sorted first!
Gotta love that beveler with the disc sander, perfect repeatability, no nubbing the fingers. If I did that the first cube would foul the disc and force me to relocate.
This gets a big 👍 for the visual appeal of the final product, you just need to set up a tent in your yard, ship in some helpers, and off to mass production while you supervise!
