100x160mm signs, featuring stylized donkey art and different words which are often commonly followed by “Ass”. As well as a blank sign for your own favorite adjective.

Print one frame and several signs, change the sign daily, and see how long it takes for your cow orkers to clue in.

Mesh and Solid models provided. The solid version might be an easier print. 
Best with color switch above 1mm, as with included gcode for the mesh version.

Also see the Shadowbox Frames, into which this and the rest of my sign collection fit.
