Note - you may need to modify the model, depending on the diameter of your racking cane/tubing. The hole in this model is 10.5mm dia. 

I’ve come up with way to make starting a siphon from my FermZilla easier and wanted to share in the hope that helpful to anyone else using a fermzilla with bottling.

Similar to the “blow to start” siphons people use with carboys.

So I 3D printed two standard PET bottle caps, each with a hole for a racking cane. Both screw directly onto the FermZilla ports.
 

One cap holds the racking cane → siphon tube → bottling wand.

The other cap has a small tube just for blowing into.

When bottling, place the wand in the bottle, push down to open and give a quick blow into the second tube.. siphon starts instantly.

I've found it super easy compared to previous method which "sucked". minimal oxygen exposure (I think).
