Scrabble Rack - Tile Holder - Solid No Supports

Based on the Scrabble Rack - Tile Holder by DagobahBen

Holes are difficult to print without support, and the long holes with round top make support and removing difficult. In addition, a solid tile rack uses less material (30g vs 25g in my defaults) as it only needs the infill not to construct walls for each hole. This solid version prints without supports.
