I'm working with the snapping tool to project a shape onto the surface of a cylinder. It worked before, but now it doesn't, and I don't know what the difference is.

An example of shape

But when I use "Snap" it does something weird at the edges:

I'm not sure what's going on here. This was my 'good' result previously (now I'm not sure how to achieve the same result again):

An example of the correct result

I've tried almost every configuration in the snap menu, but this seems to be beyond my understanding. When I achieved what I wanted, I think I used Closest, Face Nearest, Align Rotation to Target, Include Non-Edited and Move.

The Snap tool is really made to snap geometry or whole objects into place. I don't know what settings you have at the moment, it looks like it's snaping to the edges, but if you want to project an object onto another one and have it deform you should probably be using the Lattice modifier instead.

enter image description here

Create a Lattice and make it flat like in the image on the Lattice menu (the green grid tab below the modifiers tab) and put it in place. Give the fan a Lattice modifier and select the Lattice as the Object. Then give the Lattice a Shrinkwrap modifier with settings like the ones in the picture. Then set the cylinder as Target.

You also need the fan to have more geometry so that it can deform correctly. If it's a single mesh you can give it a remesh modfier set to Sharp. If it's not, you'll have to separate the parts, give and apply the Remesh modifier and then join them together again.
