Fit & tolerances Fine-tune your print

Cavity clearance mm Pin/socket fit mm

Radial allowances. Print the included fit coupon first. Cavity clearance uses a faceted spherical offset; its exact range is in the report. For models over 25k triangles, set cavity clearance to 0.

Orientation & channels For trickier shapes
