HSP differentials and drive gears have quite poor precision and the gear mesh usually needs to be adjusted.
In the design there is ~1.5mm clearance in the housing to adjust the diff position.
Print the shims and test which pair works best. You may also find that you don't need shims at all.
I currently use .4mm on the left and 1.0mm on the right meaning I set the large bevel gear closer to the drive gear for optimal mesh.
