DEC 19 2024 UPDATE:
The AMS version of this profile is poorly-optimized. I have left it here for those who may prefer the original design - but, for everyone else, I recommend the newer 7-Unit Gridfinity Ruler MKII or Gridfinity Ruler MKII Left-To-Right versions.

THE GRIDFINITY RULER [7 Unit Length]
Stop wasting time converting units - because life is short, and the meaning is 42!

Since getting into 3D printing, it has become increasingly important for me to measure everything in the known universe in 42mm increments. I wanted an quick and easy way to do this, without having to resort to pesky 3rd grade arithmetic-- a skill I have lost almost entirely. As such, I've sacrificed most of one weekend of my life to bring you (and me) a handy and kinda cute ruler, with:

• Has 42mm X/Y axis units on one side, & 7mm Z axis units on the other
• Prints in a single colour because I have harnessed the magic of light and shadow for the numbering
  • 2-Colour version now available!
• Lettering is easy-to-read printed from a 0.4mm nozzle
• Also available in 5 unit length for your A1 mini!
• For a super family heirloom quality version, print at 100% infill on a smooth PEI plate with 0.2mm nozzle. Tasty.

Use it for finding out if the models you see online will fit in your various nooks and crannies! Use it as a design aid while making bins for your most strange and exotic wrenches! Print a whole bouquet of coloured rulers for your love! Stick one in with your buddy's normal rulers and watch their face contort as they try to make heads and tails of this mysterious new scale! The sky is the limit - and the limit, of course, is multiple of 42.

If this print helped you out, send a little boost 🚀 my way - it's free! Appreciate you! :)
