Stanley Cup Cap + Straw Holder Set

This is a 3D‑printable replacement cap and straw holder designed for the intended Stanley cup geometry. It allows you to replace lost, damaged, or worn‑out parts without buying a whole new cup. The components are modeled for a precise fit, but final results depend on your printer, filament, and slicer calibration.

This upload includes:

• Replacement Cap

• Replacement Straw Holder

• Printable digital files

Stanley cup not included.

⭐ Key Features

🔄 Replacement Part

Designed as a functional 3D‑printable replacement for the corresponding original parts.

📐 Precise Fit

The geometry is modeled around the intended cup dimensions for a snug fit. Your print may require light sanding depending on printer calibration, filament shrinkage, and slicer settings.

🧩 Not Print‑In‑Place

These parts are not designed to print in place. Print separately, remove supports, clean edges, and assemble afterward.

🪚 Light Sanding May Be Needed

Fine‑grit sanding can help remove support marks, smooth edges, and improve fit. Do not aggressively sand sealing surfaces.

🧵 Recommended Filaments

🥇 PETG — Best All‑Around Choice

• Stronger and tougher than PLA

• Better heat resistance

• Good layer adhesion

• Good impact resistance

• Easy to print

Note: PETG itself is not automatically food‑safe. If the part contacts drinking liquid, use a filament specifically certified for food contact.

🥈 PP — Polypropylene

• Excellent chemical resistance

• Good fatigue resistance

• Lightweight

• Slight flexibility

• Durable

More difficult to print due to adhesion and warping.

🥉 Tritan / Copolyesters

• High impact resistance

• Good chemical resistance

• Good heat resistance

• Tough and stable

Check manufacturer documentation for food‑contact suitability.

🟡 PLA — Backup Option

Easy to print but lower heat resistance and less ideal for functional cup parts.

🖨 Recommended Print Settings

Nozzle

• 0.4 mm recommended

• 0.2 mm for finer detail

• 0.6 mm for faster/stronger prints

Layer Height

• 0.20 mm recommended

• 0.12–0.16 mm for smoother surfaces

• 0.24–0.28 mm for faster prints

Supports

Supports required where indicated. Tree/organic supports are recommended for best removal and minimal scarring.

Infill

• 15–30%

• 20% recommended

Walls / Perimeters

• 3–4 walls recommended for strength

Print Speed

Moderate speed recommended for dimensional accuracy.

🧰 Post‑Processing

1. Allow print to cool

2. Remove supports carefully

3. Clean edges (nubs, strings, blobs)

4. Test fit

5. Light sanding if needed (220–400 grit)

📏 Fitting & Tolerances

Dimensional differences may occur due to:

• Printer calibration

• Filament shrinkage

• Nozzle size

• Flow rate

• Cooling

• Layer height

• Horizontal expansion

• Print orientation

Small sanding may be required.

⚠ Food‑Contact Notice

Do not assume any 3D‑printed part is automatically food‑safe. Food‑contact suitability depends on:

• Filament certification

• Printer cleanliness

• Pigments/additives

• Layer lines

• Post‑processing

If you cannot verify food‑contact certification, treat the part as non‑food‑contact.

🧼 Cleaning

• Wash before first use

• Clean regularly

• Avoid harsh chemicals unless the filament manufacturer approves

• Inspect for cracks or wear

🛠 Troubleshooting

Too Tight?

• Check dimensional accuracy

• Check XY compensation

• Remove support artifacts

• Light sanding

Too Loose?

• Check calibration

• Check shrinkage

• Check slicer scaling

Supports Hard to Remove?

• Let print cool

• Use tree supports

• Adjust support interface settings
