Made using Autodesk 123D, I'm including the source files for you to tweak to your own needs. One has the logo, and the other is logo-less to you can put your own at the top.
This pinning tray helps keep all the parts organized when disassembling locks. The seven pin slots help you get everything back into the right chamber - something that may be important.. There's also a cutout to hold small parts like the key, empty plug, shims, screws, etc. so they don'g get lost on your work bench.
If you work on Euro profile locks, take a look at my other pinning tray before you print this one out.
Resize and orient to your own printer bed size. It works pretty well even if you scale it down quite a bit for the smaller print beds. At 80% original size and standard print quality (0.020) it takes 5 hours to print out on my Replicator 2X.
