This is my make2 of a mini basketball hoop that i made for my son.
The MK1 was prinded in 1 piece ( http://www.thingiverse.com/thing:582302) and it lasted several slam dunk but at the end has succumbed.
So i decided to make a new one but in mixed material with a metal ring that guarantee an higher resistance and better visual impact.
The ring is made with one straight aluminum bar found in a local hardware store with a diameter of 7,5mm and wall thickness of 0,8 mm.
I thought that they were perfect for my scope but I need to bend it in a circular shape so I decide to build a roll bender ... and the story can be read here http://www.thingiverse.com/thing:835165
This is bent "by hands" with an approximate diameter of 170mm
The two lower arms are made with pieces of M4 threaded bar
