Laser Cut Calliper Business Card

thingiverse

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 http://www.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 ;) Instructions I've included the .las settings file (Universal 60w Laser), but the cut order is basically: black - deep raster etch red - vector cut green - very light vector etch yellow - very deep vector etch (breakaway tabs) blue - vector cut magenta - vector cut cyan - light raster etch Current slots are made to work with 1/16th\" clear acrylic, I\'ve also etched these out of watercolour paper to hand out. They looked neat, but still took forever to etch a full run. I\'d suggest flipping the files, and back etching the cards as they look a little slicker. After the cards are cut, they should just break apart and get friction slotted together. I tried to mark the corresponding slots and tabs with matching patterns. if you need a lil refresher on how to read the scale : http://en.wikipedia.org/wiki/Vernier_scale
