Notched Dyson hose cap for DC15 vacuum

I added a Negative Volume cylinder in PrusaSlicer to create the notch. The model preview will look odd, but it's there. The original model is otherwise unchanged.

I also printed with different PrusaSlicer settings from the original — including bobstro's custom support settings and the Pretty PETG V3 filament profile. My previous print was with Prusa's silver PLA and and regular supports, and it turned out fine. For quick reference:

• Prusament orange PETG is what I had loaded
• 0.20mm layer height
• 25% infill (lower is fine)
• Support on build plate only
• 2 perimeters
