AAP-01 Hop-up helper

Source: MakerWorld by TreRitardati

The AAP-01 Hop-up helper is a free printable 3D model from MakerWorld by TreRitardati. I don't know why but the gears to set the hop up on the AAP-01 are ridiculously stiff, so i made a little geared rod to rotate them easier.   You can download the STL file from the original listing below and print it at home.
