Descrição
This is a set of upper and lower case letters that can be used for tracing. I got the idea from a coworker who had done this in another package, and it occurred to me that this is a perfect example of an OpenSCAD application.
There is an OpenSCAD file that will generate one letter, and a script that will run this for all 26 upper case and 26 lower case letters.
Here's the main OpenSCAD code. It generates the letters by extruding the text, and then rounds them off by with a Minkowsky function with a sphere. It then chops off the bottom part of the rounded letter so that the piece can be easily traced.
difference() { minkowski() { sphere(round); linear_extrude(height-round) text(letter, size=size-round, font=font); } translate([0,0,-round]) linear_extrude(round) text(letter,size=size,font=font); }
