Desktop Laser Box Joint Kerf & Tab Layout Calculator
Compute interlocking finger box joint tab counts, laser kerf offset compensation (Glowforge, xTool, LightBurn, OmTech), material caliper thickness, and snug friction snap-fit tolerances.
1. Enclosure & Material Dimensions
Nominal 1/8" = 3.0-3.3mm; Nominal 1/4" = 5.8-6.4mm.
2. Laser Optics & Fit Tolerance
Typical 40W-60W CO2 = 0.15-0.22mm; 10W-20W Diode = 0.08-0.14mm.
