Tubeless Sealant Funnel | Clean & Easy Sealant Refills
The Tubeless Sealant Funnel makes adding sealant to your tubeless tires simple, clean, and fast. It fits securely onto your valve stem and keeps the process drip-free, no need to remove the tire. Only works on Presta valves. A Fillmore-compatible version is in development and a prototype is included in the package .
A Word to the 3D Printing & MTB Community
I put a lot of time, testing, and creativity into these designs, and I trust you to use them responsibly. Shipping parts worldwide isn't great for the planet, if a few riders can print them locally, that’s already a win. Please respect my work: don’t redistribute or sell these files. Your honesty directly supports future designs for everyone.
⚠️ STL File Only
This is a digital download. You are purchasing the STL files only to print the funnel yourself. No physical product is shipped. A maximum of 3 downloads is allowed.
Print Specifications
- Material: PETG
- Nozzle: 0.4 mm
- Layer height: 0.20 mm (0.12 mm recommended for perfect threads)
- Walls: 3
- Infill: 25%

- Bed adhesion: 10 mm brim recommended
Tip: PETG works perfectly. PLA may feel looser.
You need a good printer for threads. If yours struggles, print slow (around 50 mm/s).
If the PETG threads feel too tight, try scaling up to 101%. If too loose, scale down to 99%.
