Triple MiXxx Cocktail & Longdrink Dispenser

Triple MiXxx – Modular 3‑Drink Cocktail & Longdrink Mixer

The Triple MiXxx is a compact, modular mixer designed to hold three different beverage bottles at once, making it easy to create cocktails, longdrinks, mocktails, or your own custom mixes. The clean, functional design prints quickly, assembles easily, and fits perfectly into any DIY bar setup.

Each dispensing valve has a fixed flow size, which naturally defines the mixing ratio between the drinks. By choosing different valve sizes, you can influence how much of each liquid is dispensed during mixing.

To support full customization, I’ve included the Fusion 360 source file for the valve block. This allows you to adapt the valve geometry to different bottle types or create your own flow‑rate variations.

Features

• Holds three bottles for flexible drink combinations
• Fixed‑size valves that define the mixing ratio
• Modular, easy‑to‑print design
• Ideal for cocktails, longdrinks, and creative drink experiments
• Valves fully customizable thanks to the included Fusion 360 file

A simple, fun, and maker‑friendly way to bring your drink‑mixing ideas to life.

The Assembly is pretty straight forward, each bolt just fits one hole. Just be sure not to confuse the front and the Rear, this graphic should help with everything:

Insert the wedge in the base under the channel where the mixed drink will flow through. 

The Valve assembly and O-Ring sizes and locations is shown in the graphic below:

Before screwing the valve together make sure to insert the 3D-printed spring into the rectangular cutout inside the valve block.

After Assembling the valve just stick the pvc tubing in the corresponding hole on the top side of the valve. Cut the tube to length depending of the bottle (it should easily reach the top, if the tube is to short your drink will leak out of the vent hole!

Edit: added a second base (BaseWide.stl) where all holes for the bottles are the same (biggest) diameter. Also added all valve files as fusion 360 file in a zipped archive (otherwise the upload did not work…)

Bill of materials:

• I recommend PETG for the whole print. 
• About 30cm (depends on the bottle size) of PVC Tube with an outer diameter of 5mm per bottle
• O-Rings: https://www.amazon.de/dp/B0B9H5PQ2R?ref=ppx_yo2ov_dt_b_fed_asin_title&th=1
