I came across the 3D printed tie racks which seemed rather handy, but not having a 3D printer I drafted up a file I could cut on our laser instead.

The tie slots are staggered in the hopes the ties would lay flatter against the rack.

This is an acrylic laser business card that assembles into a functional set of acrylic metric/imperial callipers, with a vernier scale accurate down to 1/20th of a mm***. Due to the size constraints of the business cards, I didn't have much room left for instructions on the card. I plan on making some screened envelopes with a 3d blowapart rendering of the unit assembly.

This file still needs some polish, but is fully functional. I was hoping to work on it a little longer before releasing it, but came across thingiverse.com/thing:782 the other day, and figured it was about time to stop trolling and register :)

Please excuse the temporary cameraphone snaps, the good camera is at a cottage for a few more days :)

UPDATE

Caliper.006 - cut files set to work with a VLS 3.60 60W

Caliper.007 - cut files adjusted to slightly looser on the friction fit.






*** depends on the accuracy of your laser cutter ;)
