Filament mixer

Please replicate the object exactly as it should be printed. Double printing will result in misaligned parts. This design accommodates 10mm fittings for 1.8id and 4mm tubing for filament. I prefer not to use 4mm od / 2mm id due to its tendency to spring back. Ensure your tubes are seated snugly within the 2 mm slots where the top fitting inserts. A small O-ring helps center the bottom one, which is flared using crafting ring pliers. Be aware that a 20mm section of tubing requires additional retraction of +20mm to clear the extrusion area. For a 20mm tube connected directly to your hotend, like in a V5 or V6 head, use 40mm retraction. This setup is based on the Trigrilla Version and works with Marlin 1.17 and later versions, supporting boards with two or more heads.
