When adding a 2230 to a HP G3 mini there is only a M4 hole and not the the M2 with a stand. This standoff helps convert the M4 hole to a M2 hole and elevates it, in this case to 3mm but Fusion 360 files are provided to change the size.
The author remixed this model.
Hex form, lower standoff (only 3mm). Also attaching Fusion 360 files with parametized dimensions.
