Making a Glass Vaporgenie alternative

Hello everybody, this is my first post, I hope your all doing well today

I am looking into trying to make an alternative to the Glass Vaporgenie due to the cost. I am planning on using the vape for a variety of substances, although I have never owned a vape nor bong so I do not know which individual parts to buy in order to replicate the device. I know I will not be able to make a device which hits as smoothly.

I live in Bristol, UK so I am looking for parts which can easily be shipped...
