Deep Strike (or 8th Edition equivalent) measuring tool.

When I was watching a couple of live games, either on Twitch or the LVO I noticed some players had measuring tools for deep striking - 9" long. Now I do have one of those laser cut plastic 6" templates, which I never really use but I could see a real benefit for one of these, particularly when I'm bringing in Trygon and friends.

Initially I was going to print a 9" strip and stick it to card but I realised I could do better than that as 12" shatterproof rulers are only 29p at Home & Bargain. So I've just picked one up, cut off the last 3" and the bit at the other end and I now have a durable and cheap tool to speed up whether I'm within range or not.
