We built a couple of iterations of the Mosquito Liquid. This is the first iteration. It works just as well as the production model, but was a little bulkier and more expensive to build. It comes with some really nice SMC KQB2 One-Touch fittings that are nickel plated. Both the fittings and cooling block are designed to be compatible with virtually any coolant.
As a nice bonus, these Mosquito Liquid hotends are available for 2.85 mm filament and as a Magnum (high flow) version.
Like everything on the prototype store, there are only a few of these units available, and when they are gone, they're gone!
Disclaimer: The limited-edition prototypes on this page carry no warranty (as there are no replacement parts in production for these units) and will not be supported post-purchase. Once these parts are gone, they are gone! All sales are final.
