Summary

A compact 3D-printable coupler designed to join two 32 mm swimming pool pipes/hoses in-line. The model uses a stepped, sleeve-style profile so each pipe can slide on and seat against a positive stop/shoulder, helping with alignment and preventing over-insertion. The internal passage remains open for unobstructed flow, and the short overall length makes it ideal for tight equipment bays or quick repairs.

Print notes: For pool use, print in PETG, ASA, or ABS (PLA tends to soften/creep from the sun). Use solid perimeters.
