Rectangular adapter downloadable as STL 3D file. Side A and side B share the same internal cross-section, 120x40 mm, with a rectangular profile. Each sleeve provides an insertion length of 20 mm. The transition section between the two sides is 80 mm long, for an overall length of 120 mm (side A sleeve, transition and side B sleeve). The internal edges at the ends are chamfered to help guide the duct during insertion. An offset of 40 mm along the Y axis and 30 mm along the Z axis is applied to side B with respect to side A.
