Rubbermaid Ladderhook

Have a rubbermaid tool cart but lost the ladder holder clips. company said they discontinued them (although a new cart has them) this is my fix. a ladderhook.

V2 - has a slightly wider gap (buddys cart was a bit wider)

I'm still new to this, as such I've been playing with infill settings to save some time.
You may want to up the wall count as this will give it added durability.
