I wanted a Dominoes tray for game play. I originally printed the versions available on Pinshape but found they were larger than necessary and used too much plastic to print.

UPDATE: I added a version that spells it out "Capicua"

I set out to design a lighter version with a smaller footprint that is stable enough for a moving table (people I play with get very excited)

I was inspired by Felix Garcia's version -https://www.thingiverse.com/thing:1873271
