Thanks to Lab3Dp's idea I was thinking how to do the same function in a more aesthetic way.

Since a few months ago I have mounted the ERCF (enraged rabbit carrot feeder) with a LGX ACE and I have always been surprised by the great fixation of the small connector on the bowden tube. It has never given me a single problem.
Based on the bondtech design I have adapted it to the Mini SB body.
As the bowden tube can pass through the push fit I have left the rest of the bownden path as it comes so that it gives an extra hold and allows the filament to be guided almost to the pulleys.
I haven't tried it on the ERCF yet but I have tested it by pulling it repeatedly with pliers without it coming out.
You need a 4mm Push-Fit Collet (in my case the bondtech one).
