Parksite Spindle Sander - Replacement Fan/Coupler

NOTE: This is my first model, so please check if I didn't make any major mistakes. This is a model of the fan and coupler in the Parkside Oscillating Spindle Sander. It acts as a fan and ensures the coupling of the spindle and belt sander to the spinning axle. The original is made of a soft material that feels like TPU. I prented it in PLA and it fit perfectly. A bit tight around the drive shaft, but with TPU it should be fine. I did not print it in TPU yet as I don't have the filament and a dryer (yet). Update 15-02-2025: Now in TPU Finally got round to buying, drying and printing in TPU.The fit is a surprisingly good friction fit with TPU. I've updated the pictures, including a sanding test.
