How do I contact the author of a Feature script?

Hello,

I am using this Feature script: Fully customizable Gridfinity Bin & Base Generator V24

Document: https://cad.onshape.com/documents/0ac6b1badcbf6139bea5b88b/v/dbe75f543656097cf1518e92/e/d208f32e9a295b216538873f

There seems to be a fault in the grid generator. According to the Gridfinity documentation the center distance of the magnet holes should be 26mm (for a 42mm grid size). But it is 25.493mm
As I made several tool for inserting the magnet into the holes, these tools fail.
