Desktop Ski Ball

My 9 y.o. son came home with a pencil sketch of a Ski Ball game and said "Dad, can we print this?" A few hours of messing around in Fusion360 and here we are! Prints with no supports unless you struggle with bridging and uses a 10mm ball bearing or similar sized marble. Depending on your tolerances it may fit together snugly or not, but you can either glue it together or just friction fit the parts for easy disassembly later. All the parts will fit on a standard 200x200 bed
