Somfy compatible anemometer blades

This impeller is compatible with the Somfy anemometer shown in the last image. The hole is for a 4.3mm shaft; it fits snugly to prevent it from detaching. This model allows you to replace each individual blade if it breaks due to hail. The blades are installed by inserting them and securing the assembly with 3 small 3 or 4mm x 15mm screws. Optionally, the tip and body can be printed as a single piece to create a unified body. I printed it with a 0.20mm layer height and 25% infill, and it is very robust even in PLA, but ABS or PETG would obviously be recommended
