I love the original design with seperated clips to be printed and pressfit. Very functional, robust and no need for supports. I just remixed the holder itself with an online voronoi generator and fused the result with the backplate of the originial one in OpenSCAD.
Make Sure to use “Mouse-ears” or similar measures to avoid warping at the corners (should be same for the origninal though)!
