Summer Waves / Poly waves (Polygroup) Pool Skimmer Outlet 32mm to 38mm

38mm Threaded Pool Fitting to 32mm Smooth Hose Adapter

This is a custom 3D printed adapter designed for use with above-ground pools like Polywave, Intex, Bestway, or Summer Waves. It features:

🔧 Features:

38mm male threaded fitting

Compatible with many standard pool return and suction ports

Tested to fit Polywave-style skimmer/pump returns

32mm smooth bore outlet

Perfect for use with 32mm Intex-style flexible pool hose

Smooth slip fit — secure with a hose clamp or cable tie

📐 Dimensions:

Threaded section OD: ~38mm

Hose smooth section ID: ~32mm

Through-hole bore: Fully open for water flow

🧵 Threads:

The thread profile was sourced from a working model and isn’t a defined BSP/NPT type — but it fits well with typical above-ground pool ports. Ideal for quick repairs, upgrades, or hose routing mods. 

🖨 Print Settings:

Material: PETG or ASA recommended (UV/weather resistant)
PLA will work though. 

Layer height: 0.2mm

Infill: 50–100% for strength

Supports: Not needed if printed upright with threads on top

Orientation: Print standing up (threads vertical)

💡 Tips:

Use Teflon tape/PTFE on the threads for a watertight seal

Add a hose clamp to secure the 32mm hose under pressure

Consider scaling the X/Y axis by -/+1% if your printer tends to over-extrude slightly — test fit recommended. I went with -0.5%

🛠 Use Cases:

Replacing a missing or broken return/suction fitting.

Adapting 38mm pool ports to 32mm Intex hoses

DIY filtration systems, heater bypasses, or vacuum lines
