3D STL file for rectangular adapter. Side A uses an internal cross-section of 220x90 mm (rectangular), whereas side B is 180x95 mm (rectangular). Both side A and side B sleeves share the same insertion length of 40 mm. The transition section between the two sides is 30 mm long, for an overall length of 110 mm (side A sleeve, transition and side B sleeve). Internal chamfers are added at the ends to make assembly and duct insertion easier.
