SnapFrames

What is SnapFrames?

SnapFrames, made by Micropolitan, is a freemium browser tool that generates 3D-printable picture frames sized to your photo or artwork. The frame is split automatically into parts that fit your build plate and snap together without glue, with prongs that hold the artwork flat and an optional kickstand, so you can frame a poster that is far larger than your printer.

You can choose picture, 3D art and floater frames, plus a lithophane light box (in beta as of September 2026), in rectangle, circle, oval, hexagon and arch shapes, with adjustable edge profiles, wood grain or patterned faces and face text. Exports include STL, and 3MF or OBJ for multi-color prints. The frames also suit lithophanes and HueForge prints.

Designing and previewing on snapframes.app is free without an account; downloading needs a free account and a paid plan, and only the Commercial plan includes the right to sell prints. A free, unlimited SnapFrames Lite with rectangle and hexagon frames runs inside Bambu Lab's MakerLab, which covers most simple photo frames.
