First Layer Test - Quick 5 squares (100/200/300 mm) Calibration

This set includes three fast first‑layer quick‑test plates, each with five simple squares for rapid adhesion checks and Z‑offset tuning.

Each plate is 0.2 mm thick , giving you clean single‑layer patches that print quickly and clearly show first‑layer quality across the bed.

Included sizes: • 100 × 100 mm — for small printers and mini beds • 200 × 200 mm — standard size (Ender‑3 class, K1 series ++) • 300 × 300 mm — for larger printers (CR‑10, Voron 2.4 300, etc.)

The models are intentionally minimal: just five flat squares placed at key points — four outer positions plus the center — making them ideal for quick checks without running a full‑bed test.

Scalable: You can freely scale the models in X/Y to match any bed size. You can also scale the model in the Z‑axis to match any specific first‑layer height (for example 0.1 mm , 0.12 mm , 0.28 mm , etc.).
