This upgrade unlocks the full potential of your machine, allowing you to finish massive prints in a fraction of the time
The Bambu High Flow Hotend (0.8mm Hardened Steel) is the ultimate heavyweight champion for speed and volume on the H2 and P2S platforms. By combining the massive 0.8mm nozzle diameter with an optimized high-flow melt zone, this unit delivers the maximum possible throughput for large-scale models and abrasive industrial materials.
This upgrade unlocks the full potential of your machine, allowing you to finish massive prints in a fraction of the time while maintaining incredible structural strength. This is a fully integrated, high-performance unit (0.8mm nozzle, heater, and heat break are inseparable) designed for a seamless, toolless installation into your toolhead.
Features
- Extreme High Flow Performance: Engineered for maximum volumetric speed. The 0.8mm bore is the ideal choice for industrial-scale parts, thick layer heights, and slashing print times on your largest projects.
- Hardened Steel Durability: The 0.8mm Hardened Steel nozzle is built to thrive under pressure. It offers extreme wear resistance against abrasive engineering filaments like Carbon Fiber (PA-CF), Glass Fiber (PA-GF), and Glow-in-the-dark materials without the risk of widening or clogging.
- Integrated Quick-Swap Design: Maintenance made simple. Replace the entire hotend unit without messy wiring or thermal paste, keeping your production line moving.
- Active Compatibility Note: If you are running an H2D (Dual-Nozzle) setup, both installed hotends must be the same size. To use this upgrade, you must install two 0.8mm units; mixing a 0.4mm and a 0.8mm nozzle is not supported.
Real-World Maker Tips (Large Format Printing)
- Strength Over Detail: The 0.8mm nozzle isn't just about speed—it’s about strength. Thicker walls and wider extrusion lines create significantly stronger bonds, making this the go-to for functional, load-bearing parts.
- Dial in Your Cooling: Because you are pushing a massive amount of molten plastic, make sure your cooling fans are performing at their peak. For materials like PLA, you may need to slow down slightly on fine details to allow the plastic to set.
- Check Your Slicer: When swapping to the 0.8mm, remember to select the correct "0.8mm Nozzle" profile in your slicer. Your layer heights can now safely go up to 0.6mm for lightning-fast prototyping!
Compatibility
- Compatible with: Bambu Lab H2D, H2S, and P2S toolheads.
- Not compatible with: Bambu Lab P1 or X1 series printers.

Solid Kids Sandals, Overpriced Like Most Kids Shoes 🌞
Size: 11 Little Kid, Color: Brown, Size: 11 Little Kid, Color: Brown
My son hasn’t worn these yet since it’s December in Indiana and sandals + snow obviously don’t mix. 😂 So this review is based on first impressions rather than long term wear.
That said, these seem wider than a lot of typical kids’ sandals, which I REALLY appreciate since we tend to have wider feet in our family. #hobbitfeet
The quality feels pretty decent overall. They’re described as lightweight, and while they’re not insanely lightweight, they do have enough weight to feel semi-sturdy and not flimsy or cheap. I like the style and color, and I think they’ll work well for my son once warmer weather hits.
My main complaint is the price. At just under $24 at the time of this review, it feels a little high for kids’ sandals and for what these are. I really feel like $20 MAX would make more sense. Kids shoes are almost always priced like adult shoes, even though they clearly use less material, and that’s hard for me to understand and wrap my mind around. Overall, these seem solid for daily wear, I just wish the price was a bit more reasonable and affordable.

Great basic and timeless design
Size: 12 Little Kid, Color: Brown
These sandals are a great find! They’re super easy to get on and off thanks to the Velcro straps, which is a huge win for little ones learning to be more independent. The fit is adjustable and secure, so they stay in place well during all kinds of play.
The cork-style footbed is comfortable and gives good support, and the overall design feels sturdy enough to handle everyday wear. They’re lightweight but still durable, and have held up really well so far.
They also have a classic, versatile look that goes with just about everything, perfect for summer outfits. Overall, a reliable, comfortable sandal that’s great for active kids. Would definitely buy again!

Great option for boys or girls
Size: 13 Little Kid, Color: Black, Size: 13 Little Kid, Color: Black
This is really more of a unisex option for a sandal. I have sandals that look like this, and both of my children have worn this style. I ordered these for my daughter, with the plan to pass them down to my son if they're not too worn when she outgrows them. The style is very minimalistic, so it goes with lots of outfits. All the straps are easily adjustable, so you can get a good fit. I would say the length is true to size, but the width is maybe a bit wide. Nevertheless, the adjustable straps really help them fit well. They feel really sturdy and I appreciate that the sole has cushion to it. My daughter has worn these every day since I got them out of the closet and they're holding up well.
