Description
EU Cap Upcycling Jar / Soft Drink Cap Jar (Flush Design)
Give a second life to your bottle caps! This model is a compact and minimalist container specifically designed to reuse soda and water bottle caps, transforming them into airtight and ultra-portable storage jars. Perfect for organizing small screws in the workshop (like M3/M4 metrics), storing components, samples, or using as pocket travel jars
🔗 Looking for a version with more capacity? If you have larger wide-mouth caps (~38mm like those from Aquarius, Fuze Tea, or juice bottles), the extended version of the collection is already available at this link: Wide-Mouth Cap Jar (38mm) | Wide-Mouth Jar
🛠️ Design Features
- Flush Aesthetic: The jar body has an exact outer diameter of 30 mm. When the cap is screwed on, it sits completely flush with the jar walls, creating a clean, aesthetic cylinder without bothersome steps
- Adapted to the New European Standard: The thread geometry has been modeled from scratch to be 100% compatible with the new European Union regulation caps (those attached to the bottle). Forget old designs where the retention ring snagged; here it screws on smoothly and seals tightly on the first try
- Pocket Dimensions: With a total height of only 50 mm (with the lid on), it offers the perfect balance between useful capacity and portability
🖨️ Print Profile Optimization
In the downloads tab, you will find the official optimized profile to avoid typical failures of narrow cylindrical parts:
- Batch Printing (4 Pieces): The profile includes a plate with 4 strategically distributed units
- Why 4 pieces?: When printing a single narrow part, the printer is forced to slow down drastically due to the "minimum layer time", which often leads to plastic overheating, loss of shine, and aesthetic flaws. By printing 4 jars at once, the machine maintains its constant flow and optimal speed, ensuring an impeccable exterior finish and a perfect thread without deformations
- Materials: PLA or PETG (if you're looking for extra chemical or thermal resistance) are recommended. No supports needed
Perfect! This way, you connect both models perfectly on MakerWorld. Anyone searching for one will immediately see that you have the other size available, which will help you get cross-downloads for both
