Huina 1580/580 thumb manual adjustable folding thumb V2

Version 2 of a thumb to pick things up. now with adjustability, full bucket width, and it doesn't block the power port on the arm when folded! still keeps full digging ability when installed no need to remove

IMPORTANT this was designed for the V4 bucket (but should work fine with others) and an Aliexpress QC. thumb should fit if your QC is >34mm wide where it connects to the arm.

When installing start with the linkage in the highest hole for storage (single one by itself up) and connect it to the thumb and arm and simply push to the arm with bucket and arm fully curled stretching the thumb as far as it will reach up
