I designed this thing to say thank you to my friend Richard Fauguet, a french artist who give me the money to buy my reprap after some work I have done for him.It's based on some of is work with tubes (sculpture), and for us two this piece (the smoke extractor) is called a "vader".Print, (better with raft, but can be made without), had a toric joint (o-ring), find a bottle of wine without cap, and put this in it.
