Gyroid after Rhino Tutorial

Having seen our old GrabCAD buddy https://grabcad.com/aled.j.taylor 's gyroid, https://grabcad.com/library/gyroid-10 I thought to myself: 'So ein ding muss ich auch haben', so I found this YouTube video: https://www.youtube.com/watch?v=eNvxOZbMErM&ab_channel=createchd and replicated the steps in Solidworks 2014, finally using the parametric relations to fine-tune the base shape until a pretty smooth transition was achieved.
