PLEASE MIRROR THE OBJECT! They will not line up perfectly if you print it twice!

This is made for 10mm fittings for 1.8id and 4mm tubing for filament! I do not like the 4mm od / 2mm id because of its spring effect! Make sure your tubes are in the 2 mm slots where your top fitting go in. I used a small o ring to keep the bottom one center and flared it with a pair of crafting ring pliers. Be aware if you have a 20mm section of tubing you need it to retract another +20mm more to clear the extrusion area! 40mm retraction if you have a 20mm tube directly to your hotend like in a v5 v6 head! This is based on the Trigrilla Version! works with marlin 1.17 and up with any board that supports 2 or more heads!
