OpenSCAD Bitmap Fonts Module

thingiverse

This OpenSCAD module allows for the creation of 3D text with Atari 8-Bit font emulation (A-Z, a-z, 0-9, punctuation). Users can create letters individually or use arrays of characters. Additionally, it includes a bitmap module to define custom fonts. This is done by passing an array of height modifiers and specifying bits per row; the module then forms cubes in a grid to create one shape. Note that OpenSCAD does not support string manipulation, so users must manually input each character. Also, when defining custom bitmaps, ensure no two bits are only connected diagonally to avoid non-manifold errors. The latest version can be found on GitHub at http://github.com/tbuser/openscad-bitmap. Examples of the module in use are available for Parametric Name Tag, Parametric Alphabet Block, and OpenSCAD Height Map on Thingiverse. To create a 2mm cube letter "A" that is 16mm wide and 5mm high, use `block_size = 2; height = 5; 8bit_char("A", 2, 5);`. To create a string of "MakerBot" using an array, use `chars = ["M","a","k","e","r","B","o","t"]; char_count = 8; 8bit_str(chars, char_count, block_size, height);`
