Another thing that might only be useful to myself, but you never know. It's a small sign encouraging people to follow protocol when they need CAD work done.  After applying some adhesive sheet magnet material on their backs, these have silently been appearing around my place of work in random places to remind people. 

Made using Maker World's make my sign tool on the Makerlab tab. The design at the right side was made in autocad, exported as WMF, then converted into SVG so that it could be imported to the sign. This sign uses 8 colours so you may need 2 AMS's or some tedious manual filament swapping :)
