Bottle Stopper / Cap for Glass Bottles

Bottle Stopper / Cap for Glass Bottles – TPU, Fast Print, No Supports, No AMS

Here's a simple yet highly functional bottle stopper for glass bottles – perfect for beer, soda, lemonade, homemade syrup, and other drinks. Printed in TPU, it's flexible, airtight, and reusable.

It's a great way to close an unfinished drink – keeps the fizz in, prevents spills in the fridge, and keeps insects out during a picnic.

Model features:

• Made from TPU – flexible, soft, and airtight material.
• Fits standard glass bottles (e.g., 0.5l beer bottles, returnable bottles).
• Super fast print – under 15–20 minutes.
• No supports needed – geometry designed for support‑free printing.
• No AMS required – single color (use any TPU filament).
• Reusable – put it on and pull it off in seconds.

Print settings:

• Material: TPU (e.g., 95A – the most common).
• Layer height: 0.2 mm.
• Infill: 15–20% (TPU itself is non‑porous).
• Supports: NOT required.
• Bed adhesion: No brim needed.
• Walls: 2–3 perimeters.
• Print time: about 10–20 minutes.

TPU printing tips:

• TPU requires direct drive (can work on Bowden setups at very low speeds).
• Reduce print speed – 15–25 mm/s.
• Turn off or limit retraction.
• Nozzle temperature: 220–230°C, bed: 50–60°C.

How to use:

1. Print the stopper in TPU.
2. Stretch it slightly and push it onto an open bottle.
3. The stopper seals the bottle – you can tilt it, transport it, or put it in the fridge.
4. To open – just pull it off.

Use cases:

• Close a half‑finished beer – keeps the carbonation for the next day.
• Homemade lemonades, syrups, juices.
• Store open drinks in the fridge without spillage.
• Transport a bottle in a bag without leaks.
• Keep insects out during a picnic.

Why print this?

• Super fast print – 15–20 minutes.
• TPU is durable and flexible – the stopper will last a long time.
• Print several in advance – always have one ready.
• Costs pennies compared to buying stoppers.
• Great as a small gift for a beer lover or as a stocking stuffer.
