E3D+VET exercise: Composite Bodies

myminifactory

This is part of a series of 30 exercises created for the E3D+VET program. The main goal of this Erasmus+ program is to immerse VET centers in 3D printing (visit https://www.e3dplusvet.eu/). There are 12 composite geometric body models, featuring six different shapes, each printed once with Braille and once with black text for high visibility. Models five and six consist of two parts. For computer or standard 8-point Braille, note the following dimensions: A Braille character consists of a maximum of six (or eight) points called a shape. The size of tactile Braille characters ranges from 6 to 7 mm, with common dimensions including point distances of 2.5 mm and point thickness of 1.5 mm (diameter). Form distances are typically 6 mm, line spacing is usually 10 mm, and point height should be at least 0.4 mm, ideally between 0.5 and 0.7 mm. For reference, visit http://www.braille.ch/abstand.htm. An appropriate font for Braille characters is included (EURO 800.ttf). The script should either be printed and colored with a black pen or printed in two colors. The color of the Braille models doesn't matter, but models with black text should be printed in light colors so that the lettering stands out well.
