Tapo C110 Focus Shims. There are a few different sizes depending on how far away you are needing to focus. These pair well with my A1 Modular Faceplate Mount. I ended up using the 0.05mm shim to achieve the focus I wanted.

On the plate there are 8 different sizes to try and one that looks different. Once you find the size that works best for you resize the piece that doesn't look like the others.

C110 Disassembly Instructions:

• Use 4 guitar picks to shim in these 4 areas:
• 
• Once picks are in place use a pry tool or a small flat head to pop the black cover off by pulling up.
• Release clips in red to free motherboard from chasis. Careful not to pull the speaker wire as you release it.
• 
• Remove the 2 screws from the bottom to release the camera lens.
• Place focuser shim on top of motherboard between lens and CMOS sensor.
• Tighten 2 screws on the bottom back down
• Re-assemble unit once happy with focus.
