SCALLOPED BUBBLE WAND

Revised perimeter follows the six outer bubble rings to reduce material.
Dimensions: 174.5 x 77.765 x 3.175 mm (6.870 x 3.062 x 0.125 inches).
Solid volume: 10,037.4 mm3 versus 13,260.7 mm3 for the original: 24.3% less.
Actual filament savings depend on slicer settings.
Seven openings, 40 rounded ridges per opening, and recessed solution grooves
are preserved. Flat underside at Z=0; print grooves upward without supports.
Import the STL using millimeters. Mesh checked as one connected watertight solid.
Bubble performance still requires a physical dip test.
