Dual extrusion test pieces

thingiverse

Some test prints are designed to help you fine-tune your dual extruder's performance. The most challenging print is the Ball in Box design, which includes built-in support for the ball itself - so don't add any additional supports when printing. These test prints were created to experiment with a new approach to using wipe towers in dual extrusion. You'll need three wipe towers and will move the head to each tower as temperatures switch from active to standby. A video demonstrating this technique is available at https://www.youtube.com/watch?v=3VuiOP-XwYI - be patient, it may appear static at first but it's actually in motion.
