Wolf Calibration & Stress Test

A compact sitting wolf figure designed specifically for testing FDM printer capabilities. At 5 cm tall, it prints fast enough for regular calibration checks while providing meaningful feedback on your printer's performance.

The model combines a recognizable shape with practical test features. The geometry challenges common printer weaknesses—overhangs, layer consistency, surface finish—while staying printable without supports on most machines.

What it tests:

• Aggressive overhang angles (tail approaching 90°, snout around 80°, body segments)

• Layer adhesion and Z-axis accuracy through the segmented body and neck

• Surface finish on curves and angled surfaces

• Fine detail capture (facial features, fur texture)

• Overall dimensional accuracy

• First layer adhesion with the flat paw base

Print specs:

• 50mm tall

• Uses approximately 9 grams of filament

• Print time: 30-40 minutes (depending on settings and printer)

• Single piece, no assembly

• Prints without supports

• Works with 0.4mm nozzles and typical layer heights

Recommended use: Try it when testing new filament, after making printer adjustments, or when dialing in a new material profile. PLA gives the cleanest results for detail evaluation. PETG is useful for checking stringing and cooling performance. The model works across most standard FDM setups.

Good as a functional test piece that doesn't look like a test piece when you're done.
