Battery powered lantern - with weck canning jar

USB-C Rechargeable Lantern for Weck Jars

This is a remix of the fantastic battery-powered lantern originally designed by @ThomPatterson. I want to express my gratitude to Thom for his excellent work on the design and the detailed instructions provided. Additionally, he was incredibly supportive and helpful in answering my questions during the remix process.

This version has been specifically adapted for the German and European market to fit Weck jars, which use a completely different thread than standard wide-mouth canning jars. The design is compatible with these jars: link to Amazon product.

Key Features of the Remix:

• Thread Adaptation: Modified to fit Weck jars commonly available in Germany/EU.
• Power Switch Upgrade: Replaced with a different switch (AliExpress link: switch model) that I had readily available.
• Smaller Cover Plate: The electronics cover plate was resized to match the smaller diameter of the selected jars.
• Improved Printability: Added draft angles to ensure it can still be printed without supports.
• Enhanced Aesthetics: Introduced rounded edges for a sleeker overall appearance.

I printed this design on my Prusa Mk4 with a layer height of 0.15mm, but it can also be printed at 0.1mm for even finer detail (Infill 15-20%). Everything still fits perfectly and works smoothly.

While the original design for Mason jars can still be used in Germany, these jars are often imported and can cost 3–4 times more than locally available Weck jars. This remix provides a more accessible and cost-effective solution for users in the German/EU market.

This lantern is perfect for indoor use, offering a stylish and functional way to light up your space. 

Thanks again to Thom Patterson for the original design!
