Chamferline: 3D-Modellierung & STL

Chamferline is 3D modeling for 3D printing, built around the numbers you measure. Type 40 and you get 40.00 mm. Drag a jaw, tap a readout, punch a hole, and see whether the part will print before you export it.

MAKE A PART

A 3D design starts as simple solids and holes.

• Boxes, cylinders, cones, spheres, tubes, wedges, polygon prisms, text and ISO metric or inch threads, each with caliper readouts for width, depth, height and diameter.
• Every shape is a Solid or a Hole. A hole cuts live and stays editable, so you can move it later.
• Our own keypad takes expressions such as 63.4+0.3 or 84/2, with a decimal comma or point by region and fractions in inch mode.
• Put a second finger down for the vernier: the drag slows to a tenth and shows one more decimal.
• Round or chamfer edges, chamfer the base against elephant's foot, lay a part flat on a face, align and distribute.

CHECK BEFORE 3D PRINTING

The print check builds the part layer by layer and marks overhangs, thin walls, bridges, islands that start in mid-air, text too small for the nozzle and anything that does not fit your plate. Auto-orient picks the position with the least overhang. You also get mass, filament length and an approximate print time.

FIT REAL OBJECTS

Measure the thing with a caliper, type the size, choose a press, snug or sliding fit, and Chamferline applies your clearance per side for your printer and material. Print the calibration coupon once, tell the app which pin fitted, and every lid, plug and pin after that is made for your printer.

FILES IN AND OUT

• Open STL, 3MF and OBJ files from any app with "Open with". A repair report shows what was closed or flipped.
• Export an STL file, 3MF or OBJ to the share sheet or any folder. STL is always written in millimetres; 3MF keeps units and colours.
• Chamferline does not slice or drive a printer: open the exported file in your slicer or your printer's app.

TEMPLATES

Box with lid, cable clip, phone stand, name plate, plant label, wall hook, spacer, nut and bolt, insert boss, drawer label, cover plate, plus the clearance (tolerance) test coupon. Type the sizes that matter and the clearances stay.

TEXT IN MANY SCRIPTS

Emboss or engrave names in Latin, Cyrillic, Greek, Arabic, Hebrew, Devanagari and Thai.

YOURS, ON YOUR PHONE

Every edit is saved, with versions you can compare and restore. Offline 3D modeling means no cloud and no network permission: everything works without a connection. Units follow your region and each one switches separately: mm, cm or inches with fractions, grams or ounces, °C or °F. For makers, students and teachers.
