The Wilfa Svart Presisjon WSP-1A / 1B is a great coffee brewer for the casual user or the enthusiast. One of the design elements for the enthusiast is the ability to use it to brew a chemex pot!
This makes the brewer a way cheaper alternative to Chemex's own Ottomatic, albeit without pulse brewing (unless you do it manually).
My only issue with it was the fact that the water wasn't spread out over the grounds but instead was focused somewhat narrowly in the center.
I created this to spread the water better, creating a better automatic chemex brew, works beautifully. The sprout itself is easily removed, while the top can stay in place even during "regular" brewing. The sprout has a short cylinder acting as a reservoar for the water and helps it from overflowing (doesn't even come close)
I printed the hanger "on it's back" instead of sideways, both pieces as 20% infill, no support.
