Since I installed Klipper on my Longer Lk1 (Also known as Alfawise U20) I looked for points that would allow me to have a nice view of the printing process.

Decided to design this part that allows a firm fixation and allow some degree of freedom of where to point the webcam.

I used this cheap webcam: https://www.aliexpress.com/item/1005005721109565.html?spm=a2g0o.order_list.order_list_main.189.5aa01802T6FiI1 Then just had to remove all the outer shell, and place it on the printed part.
