About this model

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 big - 1 x Wheel small - Drilling template (the one you like. Template 1 has an angle of 45° to align the drill more easily) 3. Assembling: - Clamp the end of the tube with a plier to protect air leake - Mount the Tube bender as shown in the picture. (The large wheel consists of 2 parts to facilitate disassembly at full bend). …
