In search of accurate measurements

This is what inspired this project. If anyone knows where to buy one of these, please let me know.

Here is an image of the .02mm version. This shows that the end of the tape is short by .42mm (it’s showing the line matching the slot at .58mm, but if you look at the 0 at the end, you will see that it’s past the 10cm mark, so ‘0’ on the tape is actually .58mm past the 1mm mark on the tape

This is a 0.1mm version showing the pin at 209.9mm

This is the 0.05mm version showing the pin at 131mm (we don’t quite have the right camera angle, but it looks like the line matches at the ‘0’ mark)

This also shows the test piece in the forground, it shows the pin spacing needed for various versions and is fast to print so that you can fine-tune the pin diameter/length, the dovetail fit, and the width of the lines.
There is a very short pin to the left of the 1, to the right of the 5, if they work well, you can print the 0.01mm version, if you have good pins between the 1 and 2 you can print the 0.02mm version, if they don’t work, you have the pins to either side of the 3 and have to stick with the 0.05mm or 0.1mm versions
