ER11 Collet Tray

I run 2 swiss lathes in my garage and they require tons of ER16 and ER11 collets to hold tooling. I got tired of them sitting in the drawer in boxes where I can't see the diameters. I made and printed the organizer to make them sit upright to expose the diameters. I can quickly find the correct collet for the size tool/drill I need now. An ER16 organizer is also available.
