A tip section of a multi-camera endoscope, the tip section comprising: a forward looking camera; a fluid tube (112, 114, 980, 982, 984); a unitary fluid channeling component (190, 990) adapted to channel fluid for insufflation and/or irrigation; and a cover designed to fit over the unitary fluid channeling component (190, 990); said unitary fluid channeling component (190, 990) comprising: a working channel adapted for the insertion of a medical tool; a front fluid channel; and a proximal opening adapted to receive the fluid tube (112, 114, 980, 982, 984), said proximal opening being in fluid flow connection with the front fluid channel; a front opening for cleaning the front camera at a distal end in said unitary fluid channeling component (190, 990), wherein said front fluid channel leads to the front opening; and wherein the unitary fluid channeling component (190, 990) is integrally formed as a unitary block comprising a proximal fluid channel component (190', 990') having an essentially cylindrical shape and a distal fluid channel component (190", 990") having a shape of a partial cylinder, characterized in that the tip section further comprises two side looking cameras; said unitary fluid channeling component (190, 990) further comprises a first side opening and a second side opening in said unitary fluid channeling component (190, 990), wherein each side opening (166a, 166b) is for cleaning one side looking camera; wherein the second side opening is internally fluidly connected to the proximal opening; a circumference groove (472, 572) fluidly connected on one side (474, 166b) to the proximal opening and on the other side fluidly connected to the first side opening, wherein the cover is tightly fitted and hermetically sealed to the groove (472, 572) for converting the groove (472, 572) into a fluid tight conduit. a forward looking camera;
