Collection of various STL-models for testing purposes. All models exist (if possible) in an ascii and and binary version. Some also exist as minified ascii-version where all unnecessary whitespace is removed.

Larger objects for testing of general functionality and performance testing.

• bunny - Stanford bunny
• gearwheel - Gearwheel with 40 teeth

Simple polytopes for feature testing

• cube - Cube from [-1, -1, -1] to [1, 1, 1]
• tetrahedron - Simplest valid STL model with just 4 faces
• tetrahedronMinusZero - Tetrahedron with some -0 instead of +0 values
• triangle - Just one face consisting of a isosceles triangle
• unitCube - Cube from [0, 0, 0] to [1, 1, 1]

• multiWordName - Name of solid consists of several words

• fourVertices.ascii - One face has 4 vertices instead of 3
• incorrectFaceCounter.bin - Number of faces and face-counter do not match
• missingFace.ascii - Model is missing 1 face
• missingNormal.ascii - Model is missing 1 normal
• quad.ascii - One face is build from a quad instead of a triangle
• singleFace.ascii - Model has only 1 face
• twoVertices.ascii - One face has 2 vertices instead of 3
• wrongHeader.bin - Header starts with "solid". This is normally reserved for ascii files only.
• wrongNormal.ascii - Model has 1 incorrect normal
• wrongNormals.ascii - Model has several incorrect normals

• redwood-data 3dscan - Dataset of more than ten thousand 3D scans of real objects.
