Tile Rack, for Rummikub game

Tile rack for Rummikub game.
The 190mm version is to replace my original rack from https://www.thingiverse.com/thing:1616558

In the picture, notice the two racks in the front are not using the stand, it works fine laying flat on table. The rack in the middle of picture has one optional extra row added to it, and the remaining racks hold 28 tiles and use the included stand. Add as many middle rows as you need to make the rack bigger.

The 200mm version was only needed if using the rack to replace the OEM rack from store bought version of the game. The factory game has slightly wider tiles then the printed version of the game. This extra 10mm allows space to hold 7 OEM tiles on each row.
