Custom Oval duct transition adapter STL file 120x80 mm to 90x70 mm – transition: 30 mm 📦#4220

Oval duct coupling provided as a STL 3D file. The internal cross-section on side A is 79x33 mm (oval), while on side B it is 46x45 mm (nearly circular). The useful sleeve length is the same on both sides, 10 mm. Between the two sleeves, the transition runs over 20 mm, resulting in an overall length of 40 mm. Both the inner and outer edges at the ends remain unchamfered.

Oval hose fitting available as a STL 3D file. On side A, the internal cross-section is 140x40 mm, whereas on side B it is 130x35 mm. On side A, the sleeve is 8 mm long, and on side B 6 mm. The transition portion extends over 20 mm and the overall length, sleeves included, is 34 mm. Internal chamfers at the ends improve assembly and make insertion smoother.

Oval connector available as a STL 3D file. On side A, the internal cross-section is 140x40 mm, whereas on side B it is 130x35 mm. The useful sleeve length on side A is 8 mm, while on side B it reaches 6 mm. The transition section between the two ends is 40 mm long, for an overall length of 54 mm (sleeve A, transition and sleeve B). The internal edges at the ends are chamfered to help guide the duct during insertion.

STL 3D file for an oval coupling. The internal cross-section on side A is 90.1x90 mm (nearly circular), while on side B it is 100x40 mm (oval). On side A, the sleeve is 50 mm long, and on side B 20 mm. The transition section is 100 mm long, for a final overall length of 170 mm. The ends are straight, with no chamfer at all. Side B is offset by 30 mm along the Y axis and 30 mm along the Z axis relative to side A.

STL 3D file for an oval hose fitting. On side A, the internal cross-section is 80.1x80 mm (nearly circular), whereas on side B it is 80x40 mm (oval). The sleeve on side A provides a useful length of 5 mm, and on side B 10 mm. The transition section is 20 mm long, for a final overall length of 35 mm. The wall is on the thicker side at 4 mm. External chamfers at the ends help with engagement and assembly within the duct system.

Oval adapter available as a STL 3D file. The internal cross-section on side A is 80x30 mm, while on side B it is 50x15 mm. The useful lengths are 20 mm (A) and 100 mm (B), respectively. The transition section between the two ends is 40 mm long, for an overall length of 160 mm (sleeve A, transition and sleeve B). A thickness of 4 mm provides good stiffness. Both the inner and outer edges at the ends remain unchamfered. Compared to side A, side B is shifted by 20 mm along the Y axis.

STL 3D file for an oval duct transition adapter. The internal cross-sections on sides A and B are identical, 60x20 mm. The useful length is consistent on both ends: 15 mm. Between the two sleeves, the transition runs over 140 mm, resulting in an overall length of 170 mm. Both the inner and outer edges at the ends remain unchamfered. An offset of 40 mm along the Y axis and 70 mm along the Z axis is applied to side B relative to side A.

Oval duct coupling provided as a STL 3D file. The internal cross-sections on sides A and B are identical, 60x20 mm. The useful length is consistent on both ends: 15 mm. The central transition occupies 140 mm, bringing the overall length to 170 mm. The ends are left without chamfers, with raw inner and outer edges. Side B is offset by 40 mm along the Y axis and 70 mm along the Z axis relative to side A.
