This 3D mesh is modeled in millimeters (mm) at 1:1 finished scale. Please review the following casting notes before slicing the wax pattern:
| Parameter | Specification |
|---|---|
| Part Name | Base-12 Meditation Vajra (144 mm) |
| Preferred Casting Alloys | C87300 Silicon Bronze (~95% Cu) or C83600 Red Brass (~85% Cu) |
| If CNC Machining Instead | C14500 Tellurium Copper (~99.5% Cu) |
| Overall Bounding Box | 144.0 mm (L) × 39.0 mm (W) × 34.1 mm (H) |
| Central Hub Diameter | ⌀ 24.0 mm nominal (24.5 mm max across the 12-sector flutes) |
| Lotus Collar Diameter | 28.7 mm envelope · 31.0 mm max across petal crests (12 petals per side) |
| Prong Geometry | 1 central shaft + 6 outer prongs per end (⌀ 4.8 mm at root, 12° taper) |
| Mesh Volume | 30.1 cm³ → finished weight ≈ 265 g in silicon bronze |
| Shrinkage Compensation | Scale mesh by +1.8% to +2.0% (1.018×) prior to wax printing |
| Surface Finishing | Left Half (−Z): 220-grit bead-blasted satin finish Right Half (+Z): Mirror buff polish |
| Process Request | Lost-wax investment casting from a 3D-printed castable resin pattern — no rubber master mold required (one-off piece) |
