Description
I designed this a couple of weeks ago. The pulleys look good when printed, but at least when using a standard .5mm nozzle, the teeth are not "sharp" enough and the timer belt slips too easy.
When MakerGear published their z pulleys ( thingiverse.com/thing:1081 ) I asked how they managed to avoid the slipping. Well, they use a .4mm nozzle...
Since MakerGear asked for my design: Here it is.
Again: These pulleys print nicely and also kind of work. The only thing is, that the timer belt doesn't get enough grip on its teeth at .5mm printing.
The gcode file contains the object, processed for .5mm nozzles!

Even with .5mm nozzle it would work perfect as an idler pulley.
Surely one could make a pulley with fewer, more exaggerated teeth, and use a belt with fewer teeth to compensate?
@Zaggo - thanks!! I printed four today, put them on and now I am trying them out. Will keep you posted on the results.
@nop.head - Thanks! That is good to know.
