About this 3D model

Most extruders won't print flexible filaments like NinjaFlex and you need to modify the drive mechanism before you can print. The creatr's extruder is basically a modified MK8 extruder, but most of the spring loaded extruders on thingiverse won't fit a Creatr or they don't properly contain flexible filament. I worked with engineers from NinjaFlex to modify my Creatr with a spring loaded extruder drive mechanism and it works awesome.
