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.).
