Size & extrude

Overall cutter width (mm)

Height stays proportional. The grip’s outer edge sets the width. Wall: 0.8 mm outward · grip: 5 mm outward.

Inside stamp

Include inward stamp ledgeBack ledge width (mm)

The ledge is at the grip end. The cutting edge stays unchanged. Build the cutter before tracing the stamp.

Trace lines over your image, or choose Fill above the editor and click a solid line to add its connected shape. Mouse strokes smooth automatically as you draw and become 0.8 mm raised ridges by default.

Stamp clearance per side (mm)

Detail width (mm)Default/max impression depth (mm)

Detail width affects drawn lines and selected colors. For color selections, 0.8 mm preserves the original thickness; higher values thicken and lower values thin. Only thin fragments created by clipping at the perimeter are removed. Interior lines are preserved, even when thinner than Detail width. Rebuild the stamp after changing settings.

Raised lines join the stamp base; overhanging strokes are automatically trimmed to its outline (0.01 mm edge allowance). The stamp has 10 mm of backing. Impression depth can reach the cutter wall height minus 10 mm. A coarse female thread is recessed into its back. The matching knob has a 25.4 mm (1 inch) grip and prints separately. Ridges taper toward the impression face and have gently rounded top edges.

Trace the stamp details, then build the stamp.

Print stamp socket-side down, details up; print knob base down. Threads use 0.25 mm radial clearance and sloped flanks/roof intended for support-free printing. Fit depends on printer calibration; test print first.

STL exports are mirrored automatically so your impression matches the readable design. Matching parts and handles are mirrored together.
