Billiards Score Keeper-Square

Nice design by Omster, Thank You.
I modified it a bit:
Bookend - Made the hole square and moved it up a bit for the larger tiles. Added slots to mount to a table/workbench. Can use double sided tape too.
Counter Tile - Made the hole square and enlarged it to 35mm - Split it so it can be printed with a dual extruder(Upper and Lower) and a 1-piece for single extruder printers.
Rail - Created a 320mm Rail that needs to be printed diagonally to fit the bed properly. This is for 320mm printers, scale this to fit your needs. I used PETG for this to help make the tiles slide a bit better but I'm sure any type of filament will work.
