Rectangular pipe adapter STL 3D file 110x110 mm to 80x80 mm – transition: 20 mm (📦 #3644)

1 object(s) - format STL
Rectangular pipe adapter STL 3D file 110x110 mm to 80x80 mm – transition: 20 mm
Rectangular tube adapter downloadable as STL 3D file. Side A uses an internal cross-section of 110x110 mm (square), whereas side B is 80x80 mm (square). Both side A and side B sleeves share the same insertion length of 30 mm. The transition section runs for 20 mm and the overall length is 80 mm, sleeves included. The internal edges at the ends are chamfered to help guide the duct during insertion.

Rectangular pipe adapter STL file 215x90 mm to 215x90 mm – transition: 20 mm (📦 #10237)

1 object(s) - format STL
Rectangular pipe adapter STL file 215x90 mm to 215x90 mm – transition: 20 mm
Rectangular adapter provided as 3D STL file. On both side A and side B, the internal cross-section is 215x90 mm, with a rectangular geometry. The sleeve insertion length is the same on both sides, 5 mm. The transition section between the two sides is 20 mm long, for an overall length of 30 mm (side A sleeve, transition and side B sleeve). Internal chamfers at the ends improve assembly and provide a smoother insertion of the mating duct.
Parameter Value Unit
side A internal width 215 mm
side A internal height 90 mm
sleeve length on side A 5 mm
side B internal width 215 mm
side B internal height 90 mm
sleeve length on side B 5 mm
thickness 3 mm
transition length 20 mm

Rectangular tube adapter STL 3D file 214x87 mm to 215x87 mm – transition: 20 mm (📦 #10241)

1 object(s) - format STL
Rectangular tube adapter STL 3D file 214x87 mm to 215x87 mm – transition: 20 mm
Rectangular pipe adapter provided as 3D STL file. Side A offers an internal cross-section of 214x87 mm (rectangular) and side B uses 215x87 mm (rectangular). Each sleeve provides an insertion length of 5 mm. Between the two sleeves, the transition section adds 20 mm, giving an overall length of 30 mm. Internal chamfers at the ends improve assembly and provide a smoother insertion of the mating duct.
Parameter Value Unit
side A internal width 214 mm
side A internal height 87 mm
sleeve length on side A 5 mm
side B internal width 215 mm
side B internal height 87 mm
sleeve length on side B 5 mm
thickness 3 mm
