Plug for LIO flavoured air device

Very simple plug for the LIO flavoured air device, I know you are supposed to fray the core a bit so it stays inside but I prefer to just use this plug. It does not fall out, the core also stays inside and it's easy to get the core out.Print with TPU, I used transparent, after a few months it got a slight yellow hue from the wood I suspect.I also tested with PLA it fits perfectly but I prefer the TPU in this case.
