New bed test for wide area height map.

thingiverse

This is made so that on a delta printer you can fine tune the heights on the bed as the printer loops around the design. Be sure to use lots of perimeters when testing to get several passes. Scale to fit your working print area, it's designed to sit within a diameter of 200mm As per the attached openscad file, which describes this object: ma=52; //This is the radius the petals deviate from. lobes=9; //(number of petals) lobrad=45; function lr(a)=sin(a*lobes)*lobrad; //(this changes the radius to form the petals) function x(a) = (ma+lr(a)) * sin(a); function y(a) = (ma+lr(a)) * cos(a); points = [ for (a = [0 : 1 : 359]) [ x(a), y(a) ] ]; linear_extrude(height=2){ difference(){ offset(r=3) {polygon(points);} polygon(points); } }
