*I designed a new version that doesn't require velcro or a separate back piece!

I was looking for a way to hang jackets and bags off of the round posts of my freestanding pull up bar. 

I designed light weigh hooks that can attach to the round bars using cable tie velcro straps. 

The larger hook is designed to be used on 1.5-2" (40-50mm) diameter poles and  uses less than 4.5 grams of filament.

The weight capacity really depends on the quality of the velcro you use. I have tested mine up to 10lbs for multiple hours but it's probably best for less than 5lbs (2.3kg).

The smaller hook is designed to be used on ¾-1" (20-26mm) diameter poles and uses around 1.5 grams of filament. It should be strong enough for coats or small accessories but is not designed for heavy weight. 

Alternative back plate that can used instead of the velcro for 1.5" diameter tube uploaded.
