Summary

So, I'm an avid DND player and DM, I always liked having small 3d printed bits on the table to help give it a bit more of a real feeling. Lately I wanted a skinnier (and quicker to make) version of the wall I had created a while back. So I tried to make this. You just put in the points you want the wall to go through, and it will make it. Sorry that the vector thing may be a bit complex, it didn't seem that hard when I was making it at first.

Notes:

A lot changes on how you make the wall, but I advise keeping the bottom the bottom.

            <div><p>So I'm still trying to find the best way to do this, (my github will probably do it better once I set that up right) but here goes nothing:</p><p>I'm using a recursive module that is basically an elaborate for loop. The extent of my error handling is if it is not a valid vector point don't make that segment. It draws a parallelogram (still working on making it sharper edges) then extrudes it wall height. Then checks to see if there are more points to be drawn and repeats.</p><p>//CUSTOMIZER VARIABLES</p><p>//  This should be a small number relative to your height of wall<br>width_Of_wall = .05;</p><p>//How tall do you want this<br>height_Of_wall = 1;</p><p>//  Vector path of wall, (wall thickness is only right angles for now), to generate a seperate path make a null/blank entry in your vector of order pairs, please note these are in whatever unit you selected earlier.<br>cords_Of_wall = [[1,0],[0,0],[0,1],[-1,1],[-1,3],[0,3],[0,4],[3,4],[4,3],[4,1],[3,1],[3,0],[2,0],[,],[1,1],[1,2],[2,2],[2,1],[1,1]];</p><p>//Basically are you using american units or real units<br>units_entered = 25.4;//[1:mm, 10:cm, 1000:meter, 25.4:inch, 304.8:foot]</p><p>//default is mm for most printers<br>desired_units_for_output = 1;//[1:mm, .1:cm, 0.001:meter, 0.0393701:inch, 0.00328084:foot]</p><p>//  This option will not appear because of the *1<br>//CUSTOMIZER VARIABLES END</p><p>width_of_wall = width_Of_wall;<br>unit_conversion_factor = units_entered<em>desired_units_for_output;<br>height_of_wall = height_Of_wall</em>unit_conversion_factor;</p><p>module make_wall_segments(cords = cords_Of_wall, number_your_on,units = 25.4) {<br>/<em>number_your_on works such that when it equals 1, that is the begining.<br>(yes I am one of those people who belives arrays<br>should have started with 1 instead of 0)<br></em>/<br>point1 = cords[number_your_on-1]<em>unit_conversion_factor;<br>point2 = cords[number_your_on]</em>unit_conversion_factor;<br>point3 = [point2[0]+width_Of_wall<em>unit_conversion_factor,point2[1]+width_Of_wall</em>unit_conversion_factor];<br>point4 = [point1[0]+width_Of_wall<em>unit_conversion_factor,point1[1]+width_Of_wall</em>unit_conversion_factor];</p><pre><code>linear_extrude(height = height_of_wall){        polygon([point1,point2,point3,point4]);    }    if(number_your_on &lt; len(cords)){        make_wall_segments(cords = cords_Of_wall,number_your_on = number_your_on+1, units = unit_conversion_factor);    }</code></pre><p>}</p><p>make_wall_segments(cords = cords_Of_wall,number_your_on = 1, units = unit_conversion_factor);</p></div>
