Berd-Air Tube Bender (3 mm)

Tried to build my own "Berd-Air"-style tube. As there are no tube bender available on thingiverse that allowing to bend a 360°- circle, I had to design my own. The procedure of bending is quiet simple:

1.Things you need:
- aluminium tube (3mm od)
- screws:
- 1 x M3 x 10 mm
- 1 x M3 x 20 mm
- 1 x M3 Nut (not necessary)
- 2 x M6 screws (as lever)
- drill (I took 1,5 mm)
- plier
- and a 3D-printer of course ;-)

2. Things to print:
- 1 x U-form
- 1 x Retainer
- 2 x Wheel bi
