old tea portioner

thingiverse

I've designed a new tea portioner that works better and requires less material, perhaps some people prefer its unique shape. Quickly measure the exact amount of tea leaves needed for one pot or any other granular materials requiring the same amount daily: Place the funnel on the measuring cup with the wider brim facing downwards on the flat surface. However, it will also work well if you place it at an angle. Pour in the tea leaves until the cup is slightly over full. Slide off the funnel while striking the measuring cup, causing any excess tea to pour back into its container. The measure now contains the precise amount of tea required. Pour it directly into the filter or teapot. I use my custom-made funnel and stand for this purpose. The STL files included are designed for 44 cm³ (44 ml) and 55 cm³ (55 ml), the exact amounts of rooibos tea needed for my two teapots, 1 dm³ (1 l) and 1.25 dm³ (1.25 l). For other sizes, please use the customizer. When you have a mass, look up its density in the FAO list or measure it yourself. The "American customary units" option in the customizer is somewhat of a joke. Americans should instead refer to the milliliters per teaspoon &c. listed on this page and visit metric4us at their convenience after printing their portioner. Using measuring spoons or scoops like things 682146 or 619626 is perfectly acceptable, except that the designer seems to think that 29.5735295625 cm³ or 14.7867647825 cm³ are useful units of measurement and won't discourage Americans – and Britons – from this habit. I still prefer this design because tilting a tea tin is easier than filling a measuring spoon, especially when there's barely enough tea left in the tin for one pot. Print Settings: Printer: CTC Bizer Rafts: Yes Supports: No Resolution: 200 microns Infill: 20% Notes: Instead of rafts, you can use a brim. The brim or raft is only necessary for the portioner part. The chute may fall over during printing unless it adheres well to the print bed. Make sure the chute is positioned on the left or right side on Mendel (Průša) style printers to prevent the y-axis acceleration force from tearing it loose. How I Designed This: I started with Soren Furbo's box and incorporated some of its ideas. There isn't much code left, but the concept remains the same. This design is also available at github. When this version is updated, please refer to the repo there for older versions. Food Safety: PLA appears to be more suitable for food use than ABS, so it's recommended to use that material. Or maybe PETG. You should clean your nozzle once to remove mineral oil and other residues. When using an oiler, choose a suitable oil like vegetable oil or Ballistol oil. The printed parts only come into contact with the food for a short time, and it is usually dry, so they should have minimal impact on the safety of the final product.

I can take no responsibility for their use.
