Summary

Score keeper for billiards & pool. Keep track of up to # innings, or play first to # against someone else, etc.

If you'd like to print in two colors, print separately and pause at Z 2mm on the bookend, and 3mm on the counter piece to switch plastic. Would be really cool to see someone print a corresponding color for each ball! I used a sharpie to blacken one of the bookend's white stripe - black side being solids, striped side's, well, you know...

You'll need four bookends - glue a set of bookends together, back to back, smooth side.
Choose how many ever counter pieces you'd like,I used 9 for mine.

To finish, you'll need some sort of 3mm diameter tube to attach the bookends together. I used a 3mm carbon fiber rod and then a couple of drops of CA on both sides of each end to lock it down tight, worked great (may need a very slight reaming if too tight).

Hope you enjoy!
