It's a simple little thing, but as Bill Engvall once said... "Here's You Sign." When your people need to be herded like sheep, you will want to have at least one of these signs on hand.
UPDATE 02/05/19 As per requested on the MyMiniFactory site page for this model, I have uploaded a version of this pointing left and another pointing right. It's up to you to know your left from your right.... God knows I don't!
NOTE Due to either a Thingiverse bug or (more likely) shadowbanning, my models no longer show up under the [Newest] listings. If you want to see more of my models, please be sure to 'follow' me.
