Have a Prusa XL or MK4 and want the best performance out of your printer? These nozzles will help you get there. The ultimate high flow abrasive resistant nozzle is here.

These high-quality 3D printing nozzles are designed specifically for use with Prusa’s latest extruder – Nextruder. Compatible with Prusa’s MK4, MK4S and XL 3D printers, they feature an all-metal filament guide which means that Nextruder’s filament path is entirely metal. This helps improve overall printer reliability and enables speedier nozzle changing.  

Higher Flow. E3D Prusa High Flow ObXidian Nozzles increase your setup's volumetric flow rate, enabling you to print faster!  

How does this work? Unlike our previous E3D High Flow Hotends (Volcano and SuperVolcano), E3D Prusa High Flow ObXidian Nozzles maintain the exact same form factor as standard E3D Prusa ObXidian Nozzles; this means there is no need to adjust your pre-existing mount and fan duct setups! E3D Prusa High Flow Brass Nozzles use a unique custom internal geometry to increase the surface area for improved thermal transfer to the filament. 

With a wear resistance orders of magnitude higher than any other E3D nozzle, ObXidian is really hard, making it the perfect nozzle for printing abrasive/filled polymers. This is achieved by pairing a tool steel insert with our new E3DLC™ coating. This specially formulated coating also embeds non-stick properties into the Nozzle itself, meaning considerably less plastic build-up around the Nozzle. 

Simplified nozzle changing. Changing a nozzle on your Prusa printer just got much easier! Waste less time changing your nozzles and more time experimenting with different sizes and materials.   

Easy identification. Each Nozzle has its size engraved into it.  

Please note: 

  • These Nozzles are only compatible with Prusa MK4 and XL 3D printers.

  • ObXidian™ coated nozzles are exceptionally wear resistant compared to other products on the market and significantly outperform other hardened nozzles. Improvements in ‘exotic’ engineering filaments mean that some new materials which include aggressive fillers, including but not limited to Polymaker’s PolyMide range (PA612-CF, PA6-CF, PA6-GF and PA12-CF), can cause significant wear on even ObXidian nozzles. E3D is actively developing even more specialist solutions for these materials. In the meantime please be aware that even the rainbows and unicorns in your ObXidian nozzle are not everlasting under extreme material conditions.

⚠️ WARNING: This product can expose you to chemicals including Mineral Oils, which is known to the State of California to cause cancer, and Lead and Nickel, which are known to the State of California to cause cancer and birth defects or other reproductive harm.

Your high-energy dog will love it!
Why did I wait so long to get one of these?!? I am the stereotypical throws-like-a-girl person, and my dog really needs to have an option that forces her to run far and fast. This is it. I can get that ball half a soccer field away at a minimum if I want. The ball is super bouncy, which adds an element of fun to her attempts to tame it and bring it back. Super worth the money (which wasn't much!). I've never had one of these before, so can't compare to the non-folding version. This one is easy to carry and fits in a drawer for storrage. No way you can fit it in a pocket, especially if you have a phone in one and dog treats in the other.

Great usability
I prefer this version over the non-foldable stick, as this one I can fit into my bag and carry it out easily. Great size and has a locking feature to prevent it from folding up when throwing. Highly recommend, my dogs love fetch and it is hard to chew if they get their hands on it.

Almost Perfect
If you’ve ever seen these things, the foldable ones are just as good as the standard ones. I just wish when you folded it up there was a way to lock it into that position. When you unfold it to play, you lock it into place with the orange locking slide so it doesn’t fold up on you. But when you’re done playing and fold it up, there’s no way to lock it into that position, it can keep unfolding if you carry it around with you, plus the orange locking slide keeps sliding up and down. It’s not a huge deal, but they could’ve made it better.
