Nozzle case

Print settings:

Orientation: models are in optimal orientation for printing.
Infill: 15%
Layer height: 0.2mm
Supports:

•  cap.stl  - middle of the model can be printed without supports. Fillets at the bottom have quite steep overhangs so a support blocker can be used as shown in pictures to generate supports only under the fillets.
• case.stl - no supports needed.
