Strong table hook; non invasive

This tablehook let's you hold up your items from the ground whereever you want. Because the design it can be placed and replaced everywhere you like. 

There are two different diameters (inner circle). 75mm and 85mm. If that still doesn't suit your need's you can always rescale the 85 mm in the slicer using the formula wanted_diameter/85. 

Good luck!
