3D-Printed Screw Hose Clamp (25-40mm) – Surprisingly Strong!

Need a durable hose clamp fast? This optimized design grips 1" hoses (25-40mm) tightly with an M12 knurled screw – no glue needed! Not for critical applications – test & help improve it!

🔧 The Plastic Clamp
After rigorous testing, this 3D-printable clamp holds far tighter than expected – but it’s NOT a certified industrial replacement. Perfect for low-risk DIY projects, gardening, or prototyping!

✅ Key Features:
✔ Adjustable 25-40mm range – Fits standard 1" hoses
✔ No supports/brim needed (It is not necessary)
✔ Includes knurled M12 screw (or you can use regular M12 metal screws)
✔ Optimized for PLA (surprisingly outperforms PETG)

⚠ Critical Safety Notes:
• DO NOT USE for automotive, gas, flammable liquids, or high-pressure systems
• Industrial clamps undergo rigorous testing – this is a prototype
• Zero liability – use at your own risk for non-critical applications

🔧 Print Tips:
• Material: PLA recommended
• Tolerances: Tight by design – may stiffen initially

⚠ Assembly Warning:
• Misassembly Risk: If the house part isn’t fully seated in the band’s groove before tightening, excessive force may crack the clamp.

🔧 NEW: Improved Tolerance Version Available!
Based on your feedback, I’ve added an alternate "house" part (hose_clamp_house-bigger_clearence.stl) with slightly looser tolerances.

Which to print first?
1️⃣ Try the original version – Most users report perfect function with PLA.
2️⃣ If assembly feels too tight, use the new "bigger clearance" house part.

Ridiculously excellent print. Funtional. Already positioned to use no supports. Used for a hose on my Intex swimming pool. You saved me a trip to the store and got summer back on track.

Thank you @user_3142567941 so much for your wonderful comment! Feedback like this truly makes my day and is exactly why I love creating and sharing 3D models. Knowing that my design helped you avoid a trip to the store and got your pool back in action is incredibly rewarding—I’m so glad it worked perfectly for you!I’d like to ask: did you have any issues with the thread fit during assembly? A few users mentioned that the original version was slightly too tight, so I later uploaded a looser variant ("house"). Now, I’m considering streamlining the design to just one version but can’t decide which one to keep—or whether a middle-ground option would be best. Since every printer behaves a bit differently, user experiences are super helpful for making that decision.If you have a moment to share your thoughts, I’d really appreciate it! Either way, thanks again for taking the time to leave such kind words. Happy printing, and enjoy your summer!

Worked great for a pool hose clamp. I did break two screws at the layer line when over tightening. I might slice with more walls but they are holding strong for now. No leaks 😁

Thank you for trying out my hose clamp model and for sharing your feedback! I'm glad it's working well for your pool hose and holding strong without leaks – that's great to hear! 😊 I'm sorry to hear about the screws breaking at the layer lines when overtightened. You're absolutely right – adding more walls in the slicer could help strengthen them. Just a quick note: this particular screw has a 40 mm diameter because I found that 45 mm could actually twist under force (kudos to you for testing its limits! 😄). However, since I was concerned about strength, I opted for 30 mm screws in my other clamp designs. If possible, could you share a few photos of where the screws broke? That would help me understand the failure points better and improve the design for future users. I really appreciate your input! Thanks again, and happy printing!

it is not working

@user_1006210779

Hello there, Thank you for your comment and the photo—they are very helpful for understanding the issue. It looks like the grooves were stripped because the small "house" (the locking tab) wasn't fully seated in the cutout on the band before it was tightened. This is a known risk if the parts aren't aligned perfectly, and it's something I actually warned about in the assembly notes, as the clamp can't handle the stress in that position. It has even happened to me during testing! I would warmly encourage you to give it another try. Please just double-check that the "house" clicks securely and fully into the cutout on the band before you apply any pressure. When correctly assembled, this clamp is very strong. This model has been printed successfully many times, and other users are happy with its strength and function once assembled correctly. I'm confident your next print will work perfectly! Thank you for your patience and for giving it another shot.

It printed great and holds extremely well. Once I tighten it, it held and didn't loosen even when it got bumped.

Please, use glue, lack, or brim.

@spaghetti3627

Looks like silk filament, which unfortunately often has poor layer adhesion (Silk is generally not recommended for a highly stressed part)

Much better than clamps produced in local factory in my location!

The designer has replied

@user_1006210779

Thanks for the encouragement, but I honestly don't believe a factory with many experts could produce worse clamps - if they know what they actually look like.

@user_1006210779

By the way, I also have a clamp for your future H2D. You might find it useful. https://makerworld.com/en/models/1482005-screw-hose-clamp-80-120mm-for-4-hoses#profileId-1547635

Please give me a better description so I know where the error happened and how to prevent it. I'm worried about adhesion, the area of contact with the bed is small, but I haven't noticed a problem. A good setting of the clearance is not easy... Perhaps the biggest problem is to keep the house in the groove of the band...
