Description

Turn your LEONARDO SUCCO 7 L glass beverage dispenser (item no. 4002541245953) into a safe, full-fledged home fermenter—ideal for beer, cider, kvass, and other fermented beverages and concoctions—with our 3D-printable holed lid and gasket.

The Leonardo dispenser comes standard with a simple screw-on lid that is very well made but lacks a gasket, making it unsuitable for fermentation. With our custom-holed lid, you can optimize your equipment for perfect control over the fermentation of your brews:

Calibrated drilling: Designed to accommodate a grommet and a standard S-shaped air vent (not included).
Optimized threading: The thread height has been adjusted to compensate for the absence of the original gasket, ensuring smooth screw-in and a secure fit.
Hermetic seal: The custom-made gasket perfectly isolates the mixture, forcing CO₂ to escape exclusively through the bubbler.

STL file for the holed lid.
STL file for the seal: Precision-fit to the millimeter for the jar and lid. Designed for printing with flexible filament (TPU) to ensure optimal compression and a tight seal.
SVG file of the joint profile: Ready for printing on paper (manual cutting template) or for importing into laser cutting software (to create the joint in the flexible material of your choice).

Our lid has been tested on batches of nearly 7 L, and its effectiveness ensures safe, stable, and controlled fermentation.

Technical Tips for 3D Printing

To ensure optimal results and safe use during fermentation, we recommend printing this lid using PETG filament. PETG offers excellent mechanical and chemical resistance and is better suited for food contact than PLA or ABS.

Printing Recommendations

Material : PETG (preferably certified for food contact).
Nozzle size: A 0.4 mm nozzle works perfectly, but a 0.6 mm nozzle is recommended for faster printing, stronger walls, and better sealing.
Layer height : 0.2 to 0.30 mm, depending on the selected nozzle size.
Wall width: To further improve the seal, consider increasing the width of the walls
Perimeters / Walls: 3 to 4 layers to ensure durability and prevent air leaks.
Top/bottom layers: 5 to 6 coats for a dense, solid finish.
Infill: A fill density of 100 % is recommended for maximum strength and a perfect seal. For faster printing, a dense fill density of 60 % (grid or gyroid pattern) is possible, but durability may be slightly reduced.
Print speed: 40 to 60 mm/s to ensure optimal interlayer adhesion and precision.
Plate temperature: 70 to 80 °C (use a textured tray or glue if necessary).
Nozzle temperature: 230 to 250 °C, depending on the brand of PETG.
Cooling: Low or minimal airflow to maximize bonding between layers.
Orientation: Print flat, with the cover facing up, for maximum mechanical strength and a clean surface finish.

Food Safety & Hygiene Tips

Choice of filament : The use of food-contact-certified PETG filament is strongly recommended. Standard PETG may be used provided that you follow strict hygiene guidelines and ensure your printer is clean. Check the manufacturer’s specifications.
Nozzle material : Choose a nozzle made of stainless steel or hardened steel, as brass nozzles may contain traces of lead.
Cleaning: Wash the printed lid thoroughly before using it for the first time. Hand washing is recommended; avoid the dishwasher, as high temperatures can warp the PETG.
Disinfection: Disinfect the lid, the vent hole, and the airlock before each fermentation using a disinfectant suitable for food contact (e.g., Star San, or boiling water if the PETG can withstand it).
Inspection: Check regularly for cracks, wear, or discoloration. Replace the lid if its structural integrity is compromised to maintain the airtight seal and hygiene of your brews.
