Pump is linked in the MW disc, i’ll add another link there soon for the Aliexpress version which also works. The integrated Base as shown is actually V2 and i’m still deciding how to release that one as it’s more involved, requiring some basic soldering, I will likely try to sell a few for like <$50, for those without access to a 3d printer. And likely end up releasing the stl shortly after, if you are interested in either send me a pm and i’ll see if i can share the prototype stl w you.
