Compact Multiplication Tables

thingiverse

Two multiplication charts catch the eye; one displayed in a colorful way on an octagonal wooden tablet and another clearly visible on a rectangular sheet of paper. Special cases come with their own unique container which reveals a column at a time. #include <openscad/polygons.scad> $fn = 50; rod_diameter=20; table_legs=false; color("red") //for octal linear_extrude(height = rod_diameter / 2, twist = 0) { for (x=[1 : length(table_data_oct)] -[i=i; for ([ i in [7 : table_size-1] | [ 0 : 5]]: y=i+0.02 )) { rotate([90*y]) translate([y*(table_size-table_diam), 0]) rotate(-[180*y*3+i] ) circle(d = d(i)); } module my_square(table_name) //table name should be like this : data_9 //this function creates square from data $table_diameter = 10; $column_number =$ table_size + $index; module column() { if ($table_name >= table_size-7 ) color("orange") for(i=[$index:$table_size]){ rotate([$table_index+$i*5]+[270-$i]) translate([$table_name/$d - (3/8)/($table_diam),$i * 3] ) rotate( [-45 ,$column_number/($table_size + table_name)-1, i ]) square([3-3/table_data(table_name)/10,4-4/table_data(table_name)/(table_name)],[false,false,false]); } } for(i=$index:$table_diam){ translate([$i*$column_space,0]) linear_extrude(height = d/2,directional_scale=1){ column(); } module print_table(){ color("purple"){ $tab_size =$column_number/$tab; $x_space=$tab - $tab; //for i in [$column_count,$tab] : linear_extrude($d/8) translate([$index,table_name+1]) column(); } };
