Handle for lifting heavy fermentation balloons

Aktualizacja u źródła: 16 sie 2026

Informacje o modelu

Heavy fermentation balloons can easily slip through your hands, these handles make it easier e.g. to lift them out of their transport baskets.

Customization:

FreeCad model is included to allow custom neck sizes.
Different sizes can be selected by the "Variant" property of the body.
Dimensions can easily be changed in the "Dim" parameter table:
- Measure the top diameter right below the topmost "collar". Add 1-2mm to allow it to slide down the neck a little bit, so the fermentation cap can still slip over the collar. Don't make it too wide, so the balloon can not slip through the handle.
- Measure the bottom diameter 3cm below the top diameter. Add 2-3mm to allow it to slide down the neck a little bit, no tight fit is required.
For FreeCad newbies: To export as STL, click "body", then use "File" -> "Export" and select "STL Mesh" (or STEP, if preferred).

Required parts:

Printing instructions:

Use a tough, ductile material, e.g. PETG (brittle materials like PLA might break without warning).
Either use supports for the upper part of the nut insert or cut sagged parts with a knife.
2 wall loops and 10% gyroid infill seem to be stable enough.
