Parametric Prusa i3 combined J-Head/object cooling system Single-Double Fan

thingiverse

I rewrote the code so you can pick single or double fan models. I also adjusted parameters to work with a 25mm fan and bumped up hotend zone size to accommodate my big 20W resistor. Using AutoBedLevelling system is handy: you'll need the mounting plate found at http://www.thingiverse.com/thing:397361 Check out instructions for more info! To pick single or double fans, I added two parameters: bottom_fan_right = true; and bottom_fan_left = false; I also included a parameter to build a parallelepiped instead of a cube for the blower fan zone. I modified some settings to fit a 25mm fan in place of the original 30mm blower fan. These changes include middle_fan_mount_screw_hole_distance = 20; // from 24; and middle_fan_mount_radius1 = 8; // from 10; To make room for my large 20W resistor, I widened the hotend space by adjusting some parameters to create a parallelepiped shape instead of a cube in the fan area. I set middle_fan_mount_size = 37; //from 30 and middle_fan_mount_size_h = 32; //middle_fan_mount_size; I also expanded the blower radius with these updates: blower_radius1 = 17; // from 13.5; and blower_pipe_radius = 17.5; // from 14. For better airflow in your print, I added more holes using nr_of_pipes = 18; //instead of 12
