Mini Speed Funnel – Reservoir, Anti-Glug, Fluted

Mini Speed Funnel – Fast Drain, Anti-Glug, Fluted (PETG Optimized)

Heyo!  Feel free to remix and adapt—please link back to this original model.  I'm an engineer and I'll be posting a ton on here.  Just getting started, but I'll have a lot of functional prints and print in places.  Feel free to engage with me and I can modify or create things at your request when I have time.  I just ask that you give me credit as I'm working for you for free…

Compact high-speed funnel designed to eliminate glugging and improve flow rate.

Features:

- Integrated speed channel to prevent airlock during pouring

- External flutes for air return and turbulence reduction

- Smooth internal geometry for fast drainage

- Compact form factor for small openings

Dimensions:

Top diameter: 50 mm

Spout diameter: 10 mm

Spout length: 30 mm

Print Settings (included in 3MF):

- Material: PETG

- Layer height: 0.2 mm

- Walls: 5 (for strength and chemical resistance)

- Infill: 20%

- Supports: none required

- It currently has a brim as it's a semi-tall object.  You can remove it or change spacing to 0.15 or 0.2 if you like.

Use Cases:

- Lab work (solvents, resins)

- Automotive fluids

- Shop and general liquid transfer

Tested design—prints reliably and drains significantly faster than standard funnels.  I'll make different versions in the future if users like it.
