Hello Discuss, I need to connect the 3 tube sections to make a bypass for a pipe that is in the way of my downspout. I don't know how to fill in the gaps. Thank you for any suggestions. Bob Roos // Downspout jog // Bob Roos // March 6, 2023 include <BOSL2/std.scad> // or screws or threading T = 1.5; L = 80; Lo = L + 2*T; Li = L - 2*T; W = 40; Wo = 40 + 2*T; Wi = W - 2*T; Hoff = 50; // Height to make offset H1 = 25; H2 = 30; H3 = 25; translate([0,0,H1+Hoff])rect_tube(size1=[L,W],size2=[Lo,Wo],h=H1,wall=T,rounding=1.50); translate([0,Hoff,0])rect_tube(size1=[L,W],size2=[L,W],h=H2,wall=T,rounding=1.50); translate([0,0,-H2-Hoff ])rect_tube(size1=[Li,Wi],size2=[L,W],h=H1,wall=T,rounding=1.50);

// Downspout jog

To me the most immediate, simplest solution seems to be to use skin() to link together 3 squares for the interior and then again 3 squares for the exterior. (Or more if you want the flat sections.) And then use difference(). You could also do this by using rect_tube to make diagonal tubes, clip them off at the top and bottom and then mate them together, if you want a more "traditional" approach. That seems more fiddly to me than the first idea. You could also do something a little fancier that didn't have corners using path_sweep() if you designed a curve that traced your pipe bypass. Maybe half a sine wave?
