I use 1.75mm filament. I used your 3mm body, and drilled it out to 4mm to fit the 4mmOD/2mmID PTFE tube and its been smooth as silk, even with the floppy PolyFlex I'm using.

I have hexagon hot ends, the PTFE tubes start flush with the hobbed bolts and butt against the tops of the hot ends.
Oh, none of that was a complaint, I've been nothing but happy with the Itty Bitty Double. Even as-is, the flexy stuff is printing really well, I just wanted to provide data.
Keep up the excellent...
Regarding the flexible filament, I took sreid55's suggestion to print the 3mm body and bore it out for a 4mmOD/2mmID PTFE tube. I won't lie, there may have been some cursing and throwing of stuff...
