Transform your Elegoo printer into a high-speed precision machine. This conversion kit replaces the standard V-wheel system with a professional MGN12H Linear Guide Rail, eliminating the common headaches of wheel wear, eccentric nut adjustments, and X-axis wobble.

Why Upgrade to Linear Rails?

The stock rubber wheels on the Neptune series can develop flat spots and require frequent tensioning. By switching to the MGN12H industrial-grade steel rail, you achieve near-zero friction and vastly improved structural rigidity—essential for the high accelerations of the Neptune 4.

Features

  • Precision Engineering: The MGN12H rail offers industrial-grade accuracy, significantly reducing "ringing" and ghosting artifacts at high print speeds.
  • Zero-Maintenance Motion: Unlike POM wheels that shed dust and wear down, this stainless steel rail is built for thousands of hours of friction-free movement.
  • Heavy-Duty Bracket: Includes a custom-engineered 2.73mm thick powder-coated sheet metal adapter designed specifically to mount your stock extruder without modification.
  • Plug-and-Play Fit: No drilling or permanent frame modifications required. The kit uses existing mounting points for a seamless transition.

The Best Disposable Dinner Plates I’ve Ever Used!
Size: 500 Count (Pack of 1), Color: Brown
The Best Disposable Dinner Plates I’ve Ever Used! We’ve been so happy with the other JOLLY CHEF products that we decided to try this larger pack of dinner plates too, and honestly, these are the best disposable dinner plates I’ve ever used. They’re sturdy, hold up well with heavier meals, and don’t get flimsy or soggy like many disposable plates do. I also appreciate that they’re made from sugarcane fiber instead of foam or plastic-coated paper products. They’ve been especially great for RV trips, family gatherings, and busy days when saving water and skipping a sink full of dishes is a huge plus. The large bulk pack is convenient to keep on hand, and I like that they’re eco-friendly and compostable while still feeling durable enough for real meals. Very happy with this purchase. I hope that this review helps you decide. I know it’s what I would’ve liked to hear when picking out compostable disposable plates.

Great paper plates
Size: 300 Count (Pack of 1), Color: Brown
I am very happy with the purchase of these plates as a healthier alternative to the coated paper plates you can buy in store. I was worried that they would get flimsy with wet foods but in my experience they hold their form and do the job intended and are durable. The size is great and allows a lot of food. I feel like thw price is fair and the quality is good. They are not decorated like the plates that are in store but I don't care about it being pretty. No harmful plastic or coating. Will definitely be a reoccurring purchase for our household.
