Intex Ultra Pool Umbrella Holder Clamp — Multi-Size Pack (20/25/30/35 mm)

What it is
A printable clamp that attaches an umbrella or support pole to the tubular frame leg of an Intex Ultra pool. One side is a semicircular cradle that holds the pole; the opposite side is a concave curve that hugs the pool leg. The whole thing is fixed with two cable (zip) ties threaded through slots in the body — no screws, no drilling. I made several variants so everyone can pick the one that matches their pole diameter, and I'm including all of them in one download. Overall body size is about 44 × 68 × 20 mm.

Variants in this pack:

• 20 mm — pole cradle Ø20 mm

• 25 mm — pole cradle Ø25 mm

• 30 mm — pole cradle Ø30 mm

• 30 mm slim — Ø30 mm cradle with a slimmer/lighter body

• 35 mm — pole cradle Ø35 mm

Measure your pole's outer diameter first and pick the closest cradle size.

Print settings

• Layer height: 0.2 mm (0.28 mm is fine for a faster, still-strong part)

• Infill: 15–30% (recommend 20% for outdoor load)

• Supports: none needed — print flat with the cradle opening facing up

• Material: PETG or ASA recommended (UV/heat resistant outdoors); PLA works but may soften/creep in direct summer sun

• Orientation: flat on the bed, cradle opening upward — layer lines then run across the clamp for best strength

• Perimeters: 3–4 walls for durability

Assembly / how to use

1. Print the variant that matches your pole diameter.

2. Set the concave (Ø40 mm) back face against the Intex pool frame leg.

3. Seat your umbrella/support pole into the semicircular cradle.

4. Feed two cable ties through the pair of slots, wrap them around the frame leg, and pull tight.

5. Trim the tie ends. Reposition the pole height as needed before final tightening.
   For a wobble-free hold, add a strip of rubber/EVA between the clamp and the pole, or double up the zip ties.
