Smart Hose Splitter

UPDATE 7: made base/bottom wall thicker - only the SCAD file was updated 
UPDATE 6: fixed and improved SCAD file
UPDATE 5: added parameters for outlet and inlet heights
UPDATE 4: fixed top cone part of the base wall issue
UPDATE 3: made the base flushed with the outlets' barbs and added print support option

UPDATE 2: added max and min thickness for the valves

UPDATE 1: I've updated the scad file to allow for different INLET and OUTLET hose sizes! Also, cleaned up the codes a bit.

Customizable hose splitter. Just change the parameters and the codes will do the rest. Great for a your aquaponics / hydroponics grow setup.

valve_number = 4; //adjust number of valves to have : determines distance between each valve
inlet_outer_radius = 6; //adjust for your inlet hose outer radius
outlet_outer_radius = 2; //adjust for your outlet hose outer radius
wall_thickness = 2; //adjust this to increase thickness of the splitter body wall
max_thickness = wall_thickness+.5; //max thickness of valve
min_thickness = wall_thickness-1.3; //min thickness of valve
smooth = 100;
print_support = true; //false to not use print support for the outlets
support_thickness = .6; // print support thickness for the outlets
