Paul Hamilton shared on Thingiverse:
This tool was based on Kaadesign’s Lens wench, Thing: 1557754
My design is suited for the Raspberry Pi Camera V2.1 and if you print two of them, you will have a 8mm socket to hold the lens base and the other end to adjust the lens.
This new version has a gap under the square end to accommodate the 7mm ribbon cable coming out of the 8mm square base.
I found that I could use the socket wench to adjust a V1.3 camera lens.
