Letter Tracing Set

prusaprinters

<p>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.</p> <p>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.</p> <p>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.</p> <p>difference() {</p> <p>minkowski() {</p> <p>sphere(round);</p> <p>linear_extrude(height-round) text(letter, size=size-round, font=font);</p> <p>}</p> <p>translate([0,0,-round]) linear_extrude(round) text(letter,size=size,font=font);</p> <p>}</p> <h3>Print Settings</h3> <p><strong>Notes:</strong></p> <p>Any resolution should be fine.</p> <p>If kids are going to play with these, it's probably a good idea to seal them in a non-toxic way so they don't collect grime, germs, etc.</p> Category: Toys & Games
