Hello, here are two little accessories I made at the request of some friends.

• Focus Marks for Arri / Preston rings (Works on the Hi5 with WCU-4 rings, who has a lip, as shown on the picture below)

  

• BNC Color Rings to help identifying SDI cables for complex video configuration. They actually fit well and don't prevent to turn the cable to remove it (I was perplex with my first print but tested it afterwards)

• 

EDIT : I added a focus mark holder to tape on your monitor or to keep in your front box
