What it does

Turns your empty Bonne Maman jar into a charming handled mug
Part of Project RE_, clever upcycling meets 3D printing
Snaps onto classic European jam jars for instant drinkware
Perfect for coffee, tea, or your favorite cold beverage
Designed by Samuel N. Bernier, refined for the FabShop V2

Give your empty jam jars a second life with this clever 3D printed kitchen accessory. The Second Life Mug handle snaps right onto a Bonne Maman jar, transforming it into a functional mug with a comfortable grip.

Born from Project RE_, an exploration of upcycling in the age of 3D printing, this design was originally conceived by Samuel N. Bernier and refined by the LeFabShop team. The V2 version is perfectly adapted to fit the classic European Bonne Maman jar, turning everyday packaging into kitchen-ready drinkware.

It's a simple, satisfying way to reduce waste while adding a little DIY charm to your morning coffee routine. Print one for yourself, or a handful to share with friends who appreciate clever, functional design.
