Patio Umbrella Pole End Cap (Custom Fit / Protective Foot)

This is a durable press-fit end cap for patio umbrella poles, designed to protect surfaces and prevent wear from exposed metal edges.

The cap fits inside the pole and features a slightly flexible wall for a snug friction fit. An extended-height version is included (shown on the left in photos), which provides improved grip and retention compared to shorter designs.

Designed based on an approximate 34.5 mm (1.35") inner diameter, measured at the end of the pole. Actual fit may vary slightly depending on internal taper or manufacturer tolerances.

Works well on decks, patios, and concrete surfaces where you want to avoid scratches or noise from contact.

In the photo of the two caps, this cap is on the left with the OEM cap on the right.

📏 Sizing / Fit

• Target pole ID: ~34.5 mm (1.35")

• Fit type: Tight press-fit

• If too tight: lightly sand outer surface

• If too loose: scale up slightly (1–2%) or shim with tape

• Scale up or down to fit your pole - I also have a pole with a 1/25"/31.6mm I.D. that will not fit as printed. Would just need to scale down a little bit.

⚙ Print Settings

• Layer Height: 0.2 mm

• Perimeters: 4-5

• Top/Bottom Layers: 4–5

• Infill: 20–30% (grid or gyroid)

• Supports: Not needed (you may get some minor stringing, depending on your machine/tuning

• Brim: Optional, not needed

🧵 Filament

• Recommended: PETG (durable, weather-resistant)

• Also works: PLA (indoor/light outdoor use)

🔧 Customization / Scaling

This model can be scaled in your slicer to fit different pole diameters.

• Scale uniformly (X/Y/Z together) to maintain proportions

• Start with small adjustments (±1–2%)

• Note: scaling also changes wall thickness and fit tolerance

For precise control of fit and wall thickness, modifying the model in CAD is recommended.

💡 Design Notes

• Extended height improves retention inside the pole

• Multiple ribs increase grip without excessive force

• Solid base resists cracking under load
