Wasserkühlung Hotend water cooling Trianglelab Arethusa liquid hotend FLSun Cube

Hello, since I've been plagued by persistent problems with the retract of my e3d hotend, I decided to switch to a water-cooled system. Suddenly, it all made sense. I opted for "Triangle hotend" because its compact design is incredibly appealing. Unfortunately, the construction leaves much to be desired - the mounting from behind seems awkwardly placed, but I prefer the front-facing approach; it's significantly easier to manage. To address this issue, I created an adapter plate that securely attaches with 2x 6mm pins, which I salvaged from an old 6mm drill. Between the adapter and the hotend, I inserted 2 mm cork as insulation to mitigate potential heat buildup during extended prints lasting up to 20 hours. For my Z sensor, I've chosen a robust 18mm model. Throughout this project, I worked with PETG material. Have fun reprinting - you'll need it!

I repurposed an old WECK preserving jar as the equalizing tank, which fits perfectly with its clamps. The holes are designed to accommodate 12mm (outside diameter) components. As the water flows back, it creates a small fountain on a plate - quite delightful! All nuts used in this project feature square designs for added stability.
