Hypercube Evolution Kraken mount with 4 berd air

Hi,

this is not tested yet...
4 berd airs are needed. It's intended for the self made version with 3mm aluminium tube (ID 2.4mm) bend with [2869014 ](https://www.thingiverse.com/thing:2869014) . All 3mm tube radii are bent with the same tool.

The big tube is a 8x7.1mm

The kraken is a chines clone (with 2.85mm support). The e3d heater-blocks are the original ones.

If printed use at least 4 perimeters and 4 top/bottom layers (The air is routed through the holder)

Updates:
- 2018-12-22 - Drilljig for berd air tube is added with a six hole pattern and 1mm drill-size. Use a threaded insert in the part 1.
Drag chain mounting brackets included. Use with 10x20 mm cable chain from
