YAY!

Just got my uRulers in South Africa- everything  in perfect condition with a swedish post stamp!

Thanks Dave!

South Africa, NOT South America.  ;)

hahaha  :-DD

Check this out:
One of my uRulers does not have the additional hole at the 1 inch mark. (Germany, Berlin)
How did that happen ?
Did one from the first (Australian Batch) slip in ?

There are following differences:
While the extra hole ones have a slight curvature, the non extra hole ruler is straight, so it can lie flat on a table.
While the extra hole ones are a little bit rough along the CM side, the non extra hole ruler is similarly smooth on both measurement edges. But the difference is really slight.

Also:
Can anyone explain all the Tables on the uRuler ? I don't really get all of them.

So there are holes from 0.4mm to 2.0mm , so you can check if your THT components would fit a specific hole.
There are example traces from 5 mil to 20 mil, so you can see how wide they are. (It would be nice to have this on the border of the ruler so you can compare it to traces on a PCB)
There are some SMD-IC leg separation gauges, from 0.4mm to 0.8mm

Then there are many tables:
From left to right
oz - µm -> How much (in oz weight) copper is used on a size ?? PCB with a cladding of µm thikness.. (How big is the reference Board for this ? 1meter x 1 meter ? )
SMD footprints -> OK, size diagram including 4 examples. including new and (old) SMD size codes. What does the POW column mean ?
mil - µm -> OK, pretty straightforward.
mm - inch formula -> OK, know that from the top of my head, but it's nice to have.
Spacing - V - int - mask - bare -> Whats this ? minimal spacing for isolation ?  int - internal layer / mask - top layer with mask / bare - top layer no mask  I guess ? What is (> 3km ) ? 3 kilometers ?
Max A SMOBC @ 0.5 oz -> WTF ? I have no idea what this is about ?
Max A SMOBC @ 1.0 oz -> WTF ? I have no idea what this is about ?
Via Amps -> Nice, you just recently posted a video on this :)
SQ PIN to DIA mm -> Again, I have no idea what this is about ? Inner surface area of a via maybe ?
EIA SMD TANTALUM -> Nope, does not ring a bell...

So if anyone knows what these tables depict, we should throw together a users guide.
I guess it's easier to use the tables once you know what they are about..

Am I the only one in Sweden who haven't got the rulers yet?

No, I'm also a swede and haven't received the rulers yet.

The same here.

For some reason I was expecting 12" rulers!

Arrived in the state of Virginia, USA today in good shape.

However, the postage meter impression is "Direct New Zealand" Auckland, not Sweden.

The rulers arrived in perfect condition two days ago. Dortmund, Germany.

They look simply awesome!

A short explanation of all tables shown would be great.
