Tấm Chêm / Nêm Cho Vòi Sen

Kind of hard to explain, but if you have a shower with a slipping head-holder thing, then this can be printed and wedged in to help it stop slipping. For use on a shower pole of 25mm.

It might break a little when you insert it, because it's so delicate. But that's also kind of the point. It's just a thin ship of plastic to help stop slippage.
