Well, the important ones, at least.
Umm, did you 3D print gummies?
Prusa printers ship with gummy bears and the assembly instructions include steps for eating prescribed amounts as you go as a reward
Unfortunately, being able to follow said instructions requires that you not immediately eat the gummy bears upon opening the box, before reading the assembly instructions. I’m told it’s a common rookie mistake.
Is this anything like the marshmallow test?
Maybe a bit. 
Ah, I figured I was missing something! Thanks for the education. Maybe one of these days I’ll quit being so cheap and buy a Prusa.
That’s what we have a makerspace for :-p
