📏 Your Strut Type A

Length: 0.0mm

Width: 40mm → ~0.0mm

Height: 90mm → ~0.0mm

🔴 Miter Cut

Angle: 18° horizontal

Both ends: YES - identical cuts

Affects: Top edge

Combined with bevel = compound

🟢 Bevel Cut

Angle: 27.8° vertical

Both ends: YES - identical cuts

Affects: Side edge

Combined with miter = compound

💡 Good Karma Hubless System: Each strut needs BOTH 18° miter AND 27.8° bevel on BOTH ends (compound angle). The rectangular cross-section with compound cuts creates perfect overlapping joints - no complex hubs required!
