Writing materials. Models come in a single piece, the only exception being scissors, which can be opened and closed by working with the two halves. This detailed models were created in SolidWorks. They are based on real objects, and are provided in real scale (metric units). Materials were defined using Blender. Several file formats are available. Being based on triangular polygons, these models are particularly good for 3D printing. A N-poly version of the pencil sharpener is also included. Textures and UV mapping for rubber and pencil are included. They are intuitive, and easy to edit. Promotional render images were made using NVIDIA Iray. Lights, shaders and cameras are not included.
