Warning: Use at own risk. Assume the fan can catastrophically fail at any moment. I did my own stress check and was confident with my own prints safety. The strength of the part is highly dependent on the material and machine settings. Also balance is important to things that are spinning aggressively. Recommend to use PETG and lay it down hot and heavy.
My spindle was always too hot for my tastes and I was going to add a tachometer. So i over sized the fan to add those features and shrouded the spindle so the air would flow over the body and cool it. I used the clamps linked as a remix and softened the edge to allow airflow and added mounting points to the sides for shrouds and dust shoes.
The tachometer was kind of worthless and finicky so I removed it but the larger fan was very good at keeping the spindle cool. So I am keeping the over sized fan and shroud.
Also I attached googly eyes because:
1.) Why not
2.) The vibration in the eyes lets me know how much vibration is in my spindle helping me set speeds and feeds similar to the sound of the bit
