Ultimate 3D Printing Torture Test

The Ultimate Print Test is a compact all-in-one benchmark designed to push your 3D printer to its limits. Instead of printing multiple models like Benchy, calibration cubes, and bridging tests separately, this model combines them into one efficient torture test. At just 40×65 mm, it exposes weaknesses in cooling, retraction, dimensional accuracy, and bridging. Perfect for dialing in a new printer, fine-tuning slicer settings, or testing new filament. Included Tests: ✅ Overhangs (various angles) ✅ Retraction/stringing test ✅ Bridging (5–25 mm) ✅ Thin & tall wall stability ✅ Circular accuracy (diameter test) ✅ Fillets & chamfers ✅ Text resolution Recommended Print Settings: Layer height: 0.12 mm Walls: 2 perimeters Infill: 5% Cooling: 100% fan speed for PLA Supports: Only if overhangs fail Print time: ~50 minutes Why print this? If your printer aces this test, you know your machine is well calibrated. If it fails, the results clearly show what needs fixing — from retraction tuning to belt tension.
