Tracker Holder for Zombicide Black Plague / Massive Darkness

I love order. So I made such holders for trackers. Now it is not lie in bulk of different packages or loose.
Two versions.
8 holes for Zombicide Black Plague
9 holes for Massive Darkness (I have not yet come this game, but there's like 3 tracks of 6 color, so only 2 bars are needed)

Postprocessing: if you use high speed and a larger layer thickness on printing, you can use a 3mm drill to pass through each hole. I had some unevennesses and trackers inserts tightly
