I printed the Justin In Case model by sottto for a buddy and he requested a Justin Time. I searched around and couldn't find one so I put this together.

I printed this with a 0.6 mm nozzle.

Changing colors mid print is easy! I used Cura to slice this print, and an Ender 3 V2 with the latest stock firmware.

Note: Older Ender 3 V2 firmware will not work. You must update to the latest version.

• Choose the layer you'd like to change colors

• In Cura, go to -> Extensions -> Post Processing -> Modify G-Code

• On the left, click Add a script

• Click Filament Change

• Where it says Layer, enter the layer number you'd like to change filament

• Print

• When the printer arrives at the layer for color change, it will beep slowly then quickly, then eject filament. The hot end will cool off and the bed will remain hot.

• Swap the filaments. Click to resume printing. Remove the excess that's extruded before printing begins.

• Congratulations! You've just completed a multi-color print!
