I printed this thing for myself and I was happy with it.
Then my wife came and wanted one too ... however ... "not so incredibly voluminous".
That's why I redesigned the thing. And because my wife always carries the children's toothbrushes as well (when travelling), I designed it as a multiple holder.
In order to offer a variable number, I have adapted my script for the Customizer.
print time: 0:20:32 (single), 1:02:53 (triple)
