Latch on cooler broke so I made a new one. Printed with Taz 5 with FlexyDually printhead, Uses 1 meter of NinjaFlex and 4 Meters of ABS. "Everywhere support" setting required. Takes about 3.5 hours to print. I overlapped the NinjaFlex and ABS models about 1mm which fuses them together for a strong binding. I found it necessary to pause at layer 14 to extrude the second head that has the NinjaFlex in preparation for quality fexible print. Ooze shield also necessary.
