Hello, I will show the bands for changing the position of the hands. There are only seven of them, and they are regulated by the buttons on the Numpad keyboard.
Adjustment buttons from 1 to 7.
Application:
1) Open the console
2) Enter each line separately
3) Done! Now you can change the position of the hands.

bind kp_end "viewmodel_fov 63; viewmodel_offset_x 1.5; viewmodel_offset_y 2; viewmodel_offset_z -2"

bind kp_downarrow "viewmodel_fov 68; viewmodel_offset_x 1.5; viewmodel_offset_z 2; viewmodel_offset_x 1.5"

bind kp_pgdn "viewmodel_fov 63; viewmodel_offset_x 1.25; viewmodel_offset_z -1.25; viewmodel_offset_x 1.25"

bind kp_leftarrow "viewmodel_fov 54; viewmodel_offset_x -2; viewmodel_offset_z -2; viewmodel_offset_x -2"

bind kp_5 "viewmodel_fov 68; viewmodel_offset_x 2; viewmodel_offset_z -1; viewmodel_offset_x 2"

bind kp_rightarrow "viewmodel_fov 54; viewmodel_offset_x 2.5; viewmodel_offset_z -2; viewmodel_offset_x 2.5"

bind kp_home "viewmodel_fov 68; viewmodel_offset_x -2; viewmodel_offset_z -2; viewmodel_offset_x -2"
