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.

Does the job but dangerous to walk with!
Does the job but dangerous to walk with: foot is sliding inside the sock if the foot was treated with cream or lotion prior. It is uncomfortable to sleep with but a necessary hurdle to heal your heels!

The really work!
Bought these or a friend with severely dry cracked feet. The change was significant and immediate. They wore them around the house for a day and that night they could already feel the difference.

Fabulously bizarre and effective
These silicone socks have to be the strangest item I have ever ordered from Amazon. However strange they are, I was pleasantly surprised with them. My order came with two pairs, and I took one pair out to wash before use. I laughed at handling them then because they were a cross between hospital socks and leftover mannequin skin…trippy. The socks dried fast, so I put on foot lotion and put the socks on. The socks are beige skin tones that cover the entire foot up to the ankle, basically booties. The silicone is very soft and makes putting on and taking off the socks easy. They are also surprisingly easy to walk around in because the bottoms have grips, again, like hospital socks. I walked on tile, hardwood, and carpet with no slipping. The booties also stayed in place with no issues. I was concerned my feet would sweat, but that didn't happen. I was able to wear them for 3 hours without sweaty feet. When I took them off, my feet were a lot more soft than before or if I had used regular socks. For reference, my feet are not terrible, but the skin around my toes is dry and peeling from my picking(gross, I know). The socks I got are a size large, which worried me because they are big, but the site said for my shoe size (9) that's what I should order, and they were right. They are the perfect size and stretchy for room. I can't believe how cool and well-thought-out these socks are, on top of working. Honestly, these are among the top 20 favorite items I've ordered from Amazon. They may look incredibly strange, and they are, but they work wonders.
