French Cleat Bench Dog Holder

I saw this on thingyverse:  https://www.thingiverse.com/thing:3355610

Other than the idea, I took nothing else from it.   I recently created a French cleat wall and I saw the thingyverse storage cup and I said "that's a good way to get those out of my toolbox".  My model is created in openscad, so everything is commented and parameterized.   In short, if you have some other round stackable item you want on a French cleat wall, this should be easily modifiable. 

I did encounter some issues printing it, and wound up printing it as shown in the screen capture with supports.   I did try printing cup base down, but it went awry when it got to starting the cleat on top of the tall support for the cleat.  I did not try rim side down.
