The Pink and Green Domino Machine

Who likes knocking down dominoes? Yeah!!!!!! Who likes setting up dominoes to be knocked down? Boo!!!!!! Who likes pink and green? Uh, well, there's granddaughters, grandsons, nieces, nephews, and, well, you get the picture... If you're like our family (we love knocking dominoes down, but can't stand setting dominoes up to be knocked down), then "The Pink and Green Domino Machine" may be the answer for you too! Our kids, grandkids, nieces, nephews and other family members like this little pink and green domino dispensing machine, and we hope you and yours do also! "The Pink and Green Domino Machine" is a "domino" dispensing machine. While it doesn't dispense commercial dominoes (well it will, but not with much success as the tolerances for commercial dominoes are not quite "standardized"), it does dispense the 3D printed dominoes in this design on almost any smooth, flat surface with 1" leading edge to leading edge spacing. If you have a steady hand and good aim, adding dominoes to the rack while "The Pink and Green Domino Machine" is in motion will keep it dispensing dominoes until you run out of 3D printed dominoes, run into an obstacle, or the batteries deplete! It misses on occasions, so it requires patience at times and close attention to the off switch, but after awhile, you'll find yourself as did we, building very long strings of dominoes with ease. After seeing Mathias Wandel's "Lego domino row building machine" (https://woodgears.ca/domino/index.html, he's an excellent woodworker, check out his site), I decided to design, 3D print and assemble my own version so that I would be much less likely to forget how to put it back together if I dropped it or if the youngsters got a hold of it (20 or so printed pieces as opposed to hundreds)! If you're a Lego enthusiast, then by all means build his design as it is very impressive! But if you're a 3D printing enthusiast, then perhaps this thing is for you!

Video of prototype without "Canopy.stl", "Rack.stl", and "Domino.stl" which better illustrates the mechanism is here: https://www.youtube.com/watch?v=QT916TMgEgs.
