The site tech for our district's high school wanted to be able to label the power cord ends in the chromebook carts. The clip is 4.8mm at the center. I modeled/test fit with the new HP chromebooks they ordered this summer.

Blank.stl is just that. Tags numbered 1-36 are in the zip file. As always, including the Fusion 360 file.
If you just want to edit the text in the Fusion 360, it's the last sketch in the timeline. Edit Feature>double-click the text and the window will pop up. You can set font, height, and the actual text.

Customizer version is here: http://www.thingiverse.com/thing:1685558

Please post made pics if you make one (or several) ;)
Likes and collects are nice and certainly appreciated, but it's a different sense of satisfaction when someone posts a made pic. TIA
