Not sure about the right tolerance for your press-fit connections? This 3D Printer Fit Tolerance Test helps you find the perfect snug fit for your projects!

How it works:

This test block features three different tolerance gaps for press-fit connections:
🔹 Left (Sharp Edges) → 0.15mm Tolerance (Tighter fit)
🔹 Middle → 0.20mm Tolerance (Balanced fit)
🔹 Right (Rounded Edges) → 0.25mm Tolerance (Looser fit)

Each of the three test pins measures 10x20mm, allowing for a precise evaluation of press-fit tolerances across different sizes.

By printing this test, you can quickly determine which tolerance works best for your 3D printer, filament, and material shrinkage. No more guesswork – just print, test, and apply the best fit to your real projects!

Why You Need This Test Block?

✅ Save Time & Material – Avoid multiple failed prints due to incorrect tolerances.
✅ Improve Your Designs – Perfect for creating press-fit joints in functional prints.
✅ Test Different Materials – See how PLA, PETG, or ABS behave with each fit.
✅ Better Assembly Experience – No more parts that are too loose or too tight!

📌 Recommended Print Settings:

• Material: PLA, PETG, ABS (try different ones!)
• Layer Height: 0.2mm
• Infill: 5-15% (for faster prints, but solid results)
• Supports: Not needed
