I needed to focus my Raspberry Pi camera but I'd already mounted it in an enclosure which prevented me from using one of the other numerous tools I'd already printed from here. So I designed a tool with a long neck so it could get inside the recessed housing.
I made the outer walls as thin as I could in the model. You'll need to make sure you're dialed in with your slicer settings to make this work. Obvious tweaks apply.
Note: This is ONLY for the V2 camera (which has four notches) vs. the V1 camera (which has 3 notches). I don't have a V1 camera or I would have done a version for that..
Vertical resolution really isn't that important because all of the detail is on the horizontal plane.
