But definitely an interesting project !

Mind you given me some cool ideas for dual extrusion projects with pla and flexible pla :-)
The watercooling works because the punch make a hole just slightly smaller than the metal tube for the filament - the silicone squeezes on the tube and makes it watertight - at least for the low circulation pressure used here.

Marc's watercooling mount has strain relief for the silicone tube, so it won't stress the tube over the seam.

I'm really excited that Marc's made the subsystems of the Zatsis (the gimballed frame extruder mounts, Titan 'flying extruder' mount. and the watercooled hotend kit) as separate incentives, at very reasonable prices.

I'm seriously considering upping my funding to cover getting 2 more hotend kits and the frame extruder mount for my other printers (since I could have all 3 on the same coolant pump loop).
