Make sure the bed isn't leveled too tight or NinjaFlex will easy buckle.
We're using NinjaFlex 85A so print at a slower speed with hotter extruder temperature.
Design files are free to download and completely editable inside of Fusion360.
Adjusting the Form
The sections are modeled inside the sculpting environment, making it easy to modify the look of the shapes by defaming the geometry.
You can adjust the length of the pattern by adding or subracting how many features are duplicated in the pattern feature.
The hole for the USB cable is controlled by changing the size of the sketch.
To give the intestine a nice twisty shape, we brought the model inside of Maya and added a non-linear deformer twist. You can play the the twist until it fits the look your going for.
We used Simplify 3D cut the bottom off the model by lowering it below the bed. This gives the model a big enough base to stick to the bed.
Check the tool path before printing to make sure we’re only using 2 shells with 0 % infill for maximum flexibly.
