First Layer Test – Full Bed Calibration (120/220/320 mm)

This set includes three ultra‑simple first‑layer test squares designed for quick adhesion checks and bed leveling.

Each plate is 0.2 mm thick , making them true single‑layer prints that finish fast and clearly show your first‑layer quality.

Included sizes: • 120 × 120 mm — fits every printer • 220 × 220 mm — standard bed size (Ender‑3 class, K1 series ++) • 320 × 320 mm — for larger printers (Voron 350, CR‑10, etc.)

The models are intentionally minimal: just flat squares with no patterns or text. This keeps them lightweight, easy to slice, and perfect for beginners — and great as a quick test print when you just want to check your first layer.

Scalable: You can freely scale the models in X/Y in your slicer to fit any bed size. You can also scale the model in the Z‑axis to match any specific first‑layer height (for example 0.08mm , 0.1 mm , 0.12 mm , 0.28 mm , etc.).
