This a part to solve a frequent problem with Shimano 105 (R7000 series) and Ultegra (R8000 series). For some reason, after a few months in use, the shifter stops engaging to chance the front gear. The solution (if there is no warranty) is to change or customize the part named "Main Lever Support" (Y63X80010), adding about 3mm to it.
I designed a slight different replacement, but with the aditional 3mm in thickness. The diferences aim to make the part stronger on thin walls and easyer to install with a shorter pin. Between the two STL files the only difference is the pin lenght
A special thanks to Youtube user 3dlx for discovering the solution. You can find his video is bellow.

Notes:
Print it slow. A little bit hotter than usual and with filament fan in 33%. Everything to make it stronger.
Print with the pin upwards, making it round and easyer to install.
