We wanted to play backgammon but sets can be expensive and ordered online, so I made one myself. It's a great way to learn and purchase a factory made set later if you like the game or use this one. It's light, great for travel, and if a piece is missing, you can print a new one in no time. I made the board on the back of a standard tournament chess mat. The checkers are d:30mm and you need 15 checkers for each color The dice cups (shakers) are working well with dices up to 16mm The checker cases are not necessary but they are not long to print and they are great for checker storage if you don't want to keep everything in a bag.
