After seeing ThatSlacker's laser-cut ruler addition, I decided to do the same, but w/ 3D printing. You can use any two colors you like, but the best results I had was a dark base and swap a brighter/lighter color for the final layers.

See notes below if you've never done a color swap before. I'll also add links to the hardware I personally used in case you're unsure what type. It doesn't really matter though, as long as the bolts are long enough to go through the arms and tighten down with the fastener. I prefer torque tops with black finish, but that's purely personal preference.

Hardware Needed for Normal Version::
4 - M4 x 15mm bolts
4 - M4 nuts

Hardware Needed for Inlay Version
4 - M4 x 12mm bolts
4 - M4 nuts

Note;
The whole thing was rigid after the first assembly. The bolts didn't slide very well, and I was pretty underwhelmed. After loosening the tops and sliding the bolts up and down the arm lengths, it cleaned up the pathway, so now it works seamlessly.

Additionally, a request was made to recreate the inlay of the OG Angle Measuring Tool. These versions supposedly allow the bolt heads to sit flush. The measurements of these inlays would mean that depending on which orientation you placed this piece (short arm on top or long arm on top), the heads of the bolts would need to fit in the following dimensions:

Short Arm Inlay:

• Depth = 3.2mm
• Width = 7.2mm

Long Arm Inlay:

• Depth = 2.8mm
• Width = 7.6mm

The pause on both of these versions should be the same, since the total depth didn't need to be adjusted for the inlays. At a later date, I may make one specifically for the hardware I used, but these would be thicker, which may cause other issues.

Cheers!
