About This Adapter
Catch the dust right at the tool, so it ends up in the vac and not in your lungs or all over the bench. This part connects the Makita 9404 dust port (25mm) to a Bosch GAS18V-10L 18V 2.6 Gallon HEPA Vac hose or fitting (35mm ID).
It is printed in PETG, so it shrugs off heat and shop solvents and will not crack like brittle PLA. The friction fit grips the hose, so you skip the tape and clamps in most setups.
Every adapter is printed to order and made in the USA, so you get a clean fit shipped to you in 2 to 3 business days.

Common questions
- Will this fit my tool?
- It is sized for the Makita 9404 dust port at about 25mm. Ports can shift a little by model year, so measure your port first and compare it to the size shown above.
- Do I need clamps or tape?
- No. Both ends are a friction fit, so they push on and grip on their own in most setups. If your hose is worn, a wrap of tape helps.
- What is it made of?
- PETG. It handles shop heat up to about 80C, shrugs off common shop solvents, and takes drops without cracking like brittle PLA.
- Can I buy just the STL file?
- Yes. Pick the download option to print it yourself. The printed and shipped option comes made to order from the US in 2 to 3 business days.
- What if it does not fit right?
- Measure your port and reach out and we will help you find the right size. If a part shows up with a print defect we will reprint it.
