About this app

Design things you can 3D print, starting with simple shapes.

Tap a box, cylinder, sphere, star or heart and it lands on the workplane. Drag it, stretch it, turn it, or type exact sizes. Make any shape a hole, group shapes together, and the holes cut right through. When it looks right, check it and save an STL file for your 3D printer.

FREE NOW, PRO LATER
Every feature is free right now. A Pro version is coming, so this app will not stay free forever. Everyone who installs it now keeps every feature free for good, including any Pro features we add later.

EASY MODE
• 11 starter shapes plus 3D text.
• Holes and groups to cut and join shapes.
• Align, flip and mirror copies.
• Round edges, hollow, taper and twist, plus rows and circles of copies.
• Big handles made for fingers, and undo for every step.

PRINT READY
• Print check: closed solid, fits your printer, overhangs, thin walls and material amount, with a fix for each warning.
• Split a model that is too big for your printer into parts with pin holes.
• Mold maker: makes silicone mold and housing halves from your model.
• Save STL and OBJ, and save and open your projects.

ADVANCED MODE (one tap)
• Sketch, extrude, revolve and bevel.
• Sculpt brushes.
• Drag the corners or edges of any shape to reshape it.

MADE FOR LEARNERS, MAKERS AND TEACHERS
• Start in minutes with no training.
• Measure as you go, in millimetres.
• No sign in needed and your projects stay on your device.
