axe Z coupler with dual extrusion material

thingiverse

I wanted to test the possibility of dual material extrusion. So designed and printed this coupler and the result is beyond my expectation. Pretty hard to craft it without visual default (tpu is so creeeeaaaamy) but easy to build it strong and reliable. This is a first try, i would gladly hear any feedback... for the next try, i will reduce the number of tpu band but make the remaining bigger.
