I had issues with the tubes slipping out of the 3d chameleon extruder even after cutting the notches in the tubes to help lock them in. I ended up making this custom mount to mount next to the extruder mount.
print with solid 100% infill
Was able to use the included PTFE adapters in the 3d Chameleon kit
I run PTFE tube through the adapter and into the 3d chameleon device
The author remixed this model.
Modified to have 4 PTFE fitting holders
