Absolutely excellent ! Printed perfectly on an Ender 3 Pro with tolerance at 0.4, both at 100% and 125% scale.
Use OpenScad to customize it BUT install 32bit version and not 64bit otherwise you will get error messages while building in OpenScad http://www.openscad.org/downloads.html).
To get a customized version with letters, you also need to add write.scad add-on files into your working folder (download them from https://www.thingiverse.com/thing:16193 and copy them in a \write subfolder where your scad file is).
Emmet, you rock !!!
