This is a fun little personal project I had as an exercise in learning Fusion 360. I split a cube into three sections and created patterns for tactile play for the younger kids :) It's a puzzle and a toy!
Be sure to enable supports with an overhang at about 60 degrees, that way it will only care about support for the male connection and the highest point in the print.
Tolerance is at .3mm with consideration for varied dimensional accuracy for different printers
Challenge: Print in Colorful Flexible Filament! Add another dimension to tactile play by making the blocks a little squishy
