Dominoes Rack Stand - three tier

I have a friend who is unable to hold multiple dominoes so I generated this 'grandstand' for him. It will fit 3 full size competition dominoes in landscape orientation (2"X1") across three tiers. The stand can therefore be used in either a 6 dominoes 4 player game or the 9 dominoes single player game.

The uploaded version does not include the persons name that the photographs illustrate. PLA 0.1mm, 5% infill with support. It is important to have the support upper gap set to at least twice the layer height to ease removal of supports from the base of the decorative dominoes on the rear wall. I printed with 0.3mm top gap.
