Workout Hydration Bottle Universal Funnel V2

The Workout Hydration Bottle Universal Funnel V2 is the ultimate accessory for triathletes and fitness enthusiasts who need a mess-free way to mix hydration powders on the go. This upgraded design features a wider base for improved stability, a threaded adapter compatible with most standard water bottles (24 mm and 27 mm threads, covering common sizes like those found on Kirkland or Gatorade bottles), and a vented structure to prevent airlocks during pouring. The funnel also includes a small grip handle for easy handling during races and a snap-fit cap to keep the spout clean when not in use. Crafted for durability and convenience, this funnel ensures your hydration mix goes straight into the bottle—no spills, no waste, even on the move. Perfect for triathlon transitions or mid-ride refills, the V2 is your go-to solution for seamless hydration prep.

3D Printing Instructions for Workout Hydration Bottle Universal Funnel V2
To create the Workout Hydration Bottle Universal Funnel V2, follow these steps for a successful 3D print. These instructions are designed for accessibility across common 3D printers, ensuring a functional and durable result.
Printer Settings:
Material: PLA or PETG (PETG is recommended for better flexibility and durability under triathlon conditions; PLA is fine for lighter use but isn’t dishwasher-safe).

Layer Height: 0.2 mm (standard resolution for a balance of detail and speed).

Infill: 20% (sufficient for strength while keeping the funnel lightweight; increase to 38% if you need extra durability).

Walls/Perimeters: 3 walls (for added sturdiness, especially around the threaded section).

Print Orientation: Print upside-down with the large base (the wider end of the funnel) on the print bed. This minimizes the need for s and ensures a smooth finish on the functional surfaces.

s: Not required if printed upside-down. The design avoids steep overhangs by tapering gradually (similar to the Water Bottle Funnel for C4 Sport Pre-workout from Cults3D). If you notice bridging issues, add minimal s for the vent holes.

Brim: Use a 5 mm brim to improve bed adhesion, especially for the threaded section, which can be prone to warping with PETG.

Print Time: Approximately 1 hour (based on a 50-minute print time for a similar funnel design on Cults3D, adjusted for the added features like the cap and handle).

Printing Steps:
Prepare the File: the STL file for the Workout Hydration Bottle Universal Funnel V2 (you’d typically host this on a platform like Cults3D or Thingiverse). Ensure the model is scaled correctly—default dimensions should be approximately 40 mm tall, with a 40 mm wide base and a 12 mm nozzle (similar to specs for water bottle funnels on STLFinder).

Slice the Model: Use your preferred slicer (e.g., Cura, PrusaSlicer) to apply the settings above. Double-check that the vent holes (small slits on the side of the funnel) are oriented to print cleanly without s.

Print the Funnel: Start the print with the large base down. Monitor the first few layers to ensure good bed adhesion. The threaded section and handle should print without issues due to the gradual taper.

Print the Snap-Fit Cap Separately: The cap should be printed flat on its top surface (the side that faces outward when attached). Use the same material and settings, with a 0.2 mm layer height and 20% infill. This small piece will take about 10-15 minutes.

Post-Processing: Remove the brim carefully with a hobby knife or flush cutters. Sand any rough edges on the threads with fine-grit sandpaper (e.g., 400 grit) to ensure a smooth fit on water bottles. Clean the funnel with warm water and mild soap—do not use a dishwasher if printed in PLA, as it can deform.

Assembly and Use:
Attach the funnel to your water bottle by screwing it onto the neck (fits 24 mm or 27 mm threads, covering most standard bottles like those from Kirkland or Gatorade).

Use the handle to hold the funnel steady while pouring your hydration mix (e.g., Precision Hydration or Tailwind). The vents will allow air to escape, preventing clogs.

Snap the cap onto the nozzle when not in use to keep it clean during your triathlon or workout.
