3D Calibration Ruler
Description
Well now you can find out!
This "thing" has 100mm rulers for each of the X, Y and Z axis and also has 1mm - 10mm holes, in 1mm increments to check that holes come out the right size in your prints!
Instructions
Measure the X,Y & Z rulers with a real ruler and see how well calibrated your printer is!
If your printer is not spot on, you can use this information to update your steps/mm values in your printer firmware's configuration.h file.
This is my first "Thing" that i've created so if you have any suggestions/comments for improving it .. let me know!
Now updated to Version 2 - with a hole gauge on the Y-Axis as well as the Z-Axis as requested by Se5A.

This is cool but when you find issues your gonna need a lot of iterations callibrating. Try the callibration cube first : it's 2 by 2 by 2 cm and has a 1 cm hole. Print a couple of these fixing all issues then start print on one scaled to 500 % on x,y that will give you 10 by 10 cm which you can stop after a few layers and repeat if it's not accurate. The cube is super fast in slicing and prints in less than 10minutes:
Yes, this uses write.scad library for the text.. just download write.scad and put it in the same folder as the ruler scad file before you open it and it should work fine..
Hmmm...crashes OpenScad. Looks like it relies on write.scad. :-(
good stuff, I'm printing it now.
if there was another ruler going diagnollay between x+y far ends, I think it would show if x+y were truly perpendicular.
same with x+z and y+z.
now 100% sure since geometry was a long time ago, but it's something like that. :-)
This is very cool, I'd suggest putting holes along one of the x or y axes as well as the z.

I love this print! Not only a good calibration print, but a handy tool for use afterwards.
For the Z-height measurement, I have 101mm for the Z-ruler. the ruler measuring itself seemed fine, but the thickness of the plate is 2mm and ruler starts at the bottom of the plate at 1mm.
Is this a build issue or a flaw to be corrected? :)
(total lengths X 124.31mm, Y 126.28mm, Z 104.07mm) were the total lengths also designed for specific length? My X and Y rulers ended with a good 100mm each. They seemed pretty spot on, but I cant read it more accurate than that.
