Cánh quạt Flymo (Flymo Impeller)

This impeller fits many variants of the Flymo Lawnmover.

Before printing the larger parts, print the test-1 and test-2 models first to see if it fits the axel of  your variant of the Flymo lawnmower. If it doesn't fit, no need to print the larger partd, but drop me a message here and maybe I can upload a model matching your requirements.

Original Flymo Impeller for comparison. With 17 blades. This model has 18.

For printing top and bottom, use at least 3 walls or better 5 walls. Use at least 4 bottom  and top layers and use at least 35-40 % cubic or better infill. Top and bottom part printed without support are supposed to be glued together.

ABS or ASA is a suitable material to  use. You can also use  Nylon PA6 or PA12, but that is more expensive. PLA will splinter and break especially in cold weather. PETG is unknown and hard to glue for this task. More exotic materials can also be used, but then buying a new injection molded impeller is probably cheaper and better.

The model "Flymo Impeller-Full" is the full impeller with top and bottom in one piece. This full model will have to be printed with support and even with support, the result will often be below par or below what is desired. Therefor it is recommended to print the bottom and top model and then glue these two parts together.
