Regarding tape, yes, I have read about the dangers. I figured if it’s duct tape and on the cool end of the cage it would minimize the risk (at least until I can get a more permanent solution), but I guess it probably does not make sense to take the risk.
As an aside, I live in Switzerland. Reptile/snake supplies are fairly thin to come by. f”Frozen food/heating solutions are no issue, but acquarium decorations are more difficult to source. Ordering from abroad is difficult, if they even deliver to Switzerland, as it is not technically in the EU. So the few places that do deliver often charge excessive shipping and/or import duties.
Here is a second I made, but it is even less opaque than the first.
