A Pixel 5 compatible phone case printed in PETG and NinjaFlex TPU One version is plain, the other has the Instructables logo on the back. For the Robot case: First 3 layers (0.2mm layer height) in yellow PETG (@240C) Next 2 layers in black PETG (@240C) The rest in NinjaFlex TPU (@230C, at 30% speed) For the plain case: First 5 layers (0.2mm layer height) in PETG (@240C) The rest in NinjaFlex TPU (@230C, at 30% speed) Prusa Mk3s For the NinjaFlex, before the end of the black layer (a few seconds to go), I reduce the speed to 30%, and reduce the temperature to 230C. I remove the black using a filament change that was added in Prusa Slicer. I loosen the extruder screw, and add the NinjaFlex TPU. I then monitor the print for the first couple of minutes, making sure it is extruding properly. Sometimes I need to force another filament change to get the NinjaFlex flowing correctly, but have succeeded in all but my first attempt. It is worth becoming comfortable with NinjaFlex TPU before attempting this.
