Lego Technic Ruler and Sorting Tool

Recently bought a lot of Lego Technic sets and decided that it would be nice to have a tool I could use to make sorting Technic beams and axles easier.

I stumbled upon Tom Alphin’s printable ruler a while ago and I thought it’d be a neat idea to use the Glowforge to engrave that design into some material so that I could actually fit the pieces into something physically instead of just overlaying it on some paper.

First attempt I botched pretty hard as I forgot to make sure the design was set to the correct scale in the GFUI. Second attempt I fixed the scaling issues and tweaked the design to make it take up significantly less space / use less material. Went with some leftover Proofgrade Clear Acrylic and it turned out amazing.


Tom’s design here:


Hmm scale was off in the UI? What software do you use to design?

I typically use inkscape but I did not have my document dimensions set correctly, so when saving as an SVG and importing into GFUI it didn’t load at the correct scale. After tweaking a bunch of things and ensuring the document was saved correctly everything was 100% accurate.

Welcome to Technic. You’ll soon be able to scan them all by eye. :slight_smile:

This is AWESOME. As the owner of MANY Technique sets, this will be a lifesaver / God send to have when constructing. I agree with quixotequest in that you’ll be able to (usually) scan them by eye, but more often than not, I end up checking with the front of the book. Not any more!

Yeah I have a ton of kits, I usually have problems determining the 13s from the 15s as well as a few of the axle lengths


Very cool! I think acrylic templates and rulers is one of the most useful things you can make.
