Wall Generator for table top games

thingiverse

So, I'm a huge DND player and DM, always loved having small 3D printed bits on the table to give it that real feel. Lately, I wanted a thinner (and quicker to make) version of the wall I had created before, so I tried making this. You just input the points you want the wall to go through, and it does it. Sorry if the vector thing seems complex; it didn't seem that hard when I made it. Print Settings Notes: A lot changes how you make the wall, but I advise keeping the bottom at the bottom. How I Designed This Code Explanation So, I'm still trying to figure out the best way to do this, (my GitHub might do it better once I get it set up right) but here goes nothing: I'm using a recursive module that's basically an elaborate for loop. The extent of my error handling is if it's 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. // CUSTOMIZER VARIABLES // This should be a small number relative to your wall's height width_of_wall = .05; // How tall do you want this? height_of_wall = 1; // Vector path of the wall, (wall thickness is only right angles for now), to generate a separate path make a null/blank entry in your vector of order pairs, please note these are in whatever unit you selected earlier. 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],[2],[1,1],[1,2],[2,2],[2,1],[1,1]]; // Basically are you using American units or real units? units_entered = 25.4; // [1:mm, 10:cm, 1000:meter, 25.4:inch, 304.8:foot] // Default is mm for most printers desired_units_for_output = 1; // [1:mm, .1:cm, 0.001:meter, 0.0393701:inch, 0.00328084:foot] // This option will not appear because of the *1 // CUSTOMIZER VARIABLES END width_of_wall = width_of_wall; unit_conversion_factor = units_entered / desired_units_for_output; height_of_wall = height_of_wall * unit_conversion_factor; module make_wall_segments(cords = cords_of_wall, number_your_on, units = 25.4) { // Number_your_on works such that when it equals 1, that is the beginning. (Yes I am one of those people who believes arrays should have started with 1 instead of 0) point1 = cords[number_your_on-1] * unit_conversion_factor; point2 = cords[number_your_on] * unit_conversion_factor; point3 = [point2[0]+width_of_wall*unit_conversion_factor,point2[1]+width_of_wall*unit_conversion_factor]; point4 = [point1[0]+width_of_wall*unit_conversion_factor,point1[1]+width_of_wall*unit_conversion_factor]; linear_extrude(height = height_of_wall){ polygon([point1,point2,point3,point4]); } if(number_your_on < len(cords)){ make_wall_segments(cords = cords_of_wall,number_your_on = number_your_on+1, units = unit_conversion_factor); } } make_wall_segments(cords = cords_of_wall,number_your_on = 1, units = unit_conversion_factor);
