When will you be selling the final product of assembled Thing? 
@denix I’m guessing it will be a few more months for the whole thing, there are a few things I want to improve in addition to finding someone to actually produce it:)
What’s the estimated cost so far, do you know?
@denix The whole printer will be in the $1500-$2000 range depending on volume and final component manufacture process.
