S hook hanger

### Why

I bought a horizontal bar to hang my (empty) camera bags from, but forgot to buy the hooks that go with it.
Rather than go back to the store I spent way more time designing and printing the hangers myself.

I ended up printing mine with PETG at 60% size, 3 perimeters, 15% infill and 3 top/bottom layers and they hold up just fine.

### Features

* Can accomodate a 40mm diameter bar at 100% scale
* Designed for strength (chamfered edges make it stronger...I think)
* Can be scaled up or down in your slicer to accomodate other bar sizes
* Shaped like an "S" (I'm really stretching the features here)

### Instructions

* Print it in PETG with multiple walls and slow speed to get the strongest part.
* Print without a fan to get the strongest part.
* No supports required
* Prints fine at 0.3mm layer height, but lower heights should work just as well.
