Are you looking to buy a Rat Rig  V-Core 3 Upgrade Kit (v3.0 to v3.1) in Australia?

STRONGER. SMOOTHER. EASIER. THE NEW V-CORE 3.1 IS HERE!

 

 

BETTER THAN EVER.

After over a year of production and thousands of units delivered to customers worldwide, we can say we learned a lot! Now, we're bringing all those lessons to the newest iteration of the V-Core: Version 3.1! More robust than ever, much easier to put together, and with little polishes all over the design.

 
 

EASIER BUILD

    • Reverse frame build makes it much easier to get the frame square where it matters the most. Build from the top down with a flat XY top section, eliminating skew and bed mesh problems later

 

    • No more Z alignment, plug & play installation

 

  • New build manual
 

MORE ROBUST KINEMATICS

New XY idlers with much bigger bearings. Smoother, stronger and more long lasting.

 

MORE TOLERANT DESIGN

The completely redesigned Z axis with decouplers makes the machine far less sensitive to part issues and builder errors

 

KIT CONTENTS

The base kit includes all mechanical parts to perform the upgrade, including fasteners for the EVA 3 assemblies supported by Rat Rig (Extruders: Orbiter 2, LGX, LGX Lite / Hot-ends: Rapido, Mosquito, Mosquito Magnum). The only part that is dependent on machine size is the belt, which we ship in a length long enough for the largest machine size.

If you purchase the Printed Part Set, it will include all essential V-Core 3.1 Printed Parts (some cable management parts are not included), including EVA 3 Parts to mount your extruder and hot-end selection, along with the new fan duct for the new 4028 Fan.

Prefect Travel Case
Color: Black, Color: Black
I got this for taking my jewelry on the go. I have to say that I was pleasantly surprised by the quality it feels very sturdy. It has several spots to hold jewelry and keep it organized. The outside is textured and it closes with a snap which can be done easily.

Small, bu holds a lot
Color: Black
I initially purchased the Jewelry Box Necklace Ring Storage Organizer as a gift for my 8-year-old daughter. The compact design and practical features seemed perfect for her little trinkets. However, its quality and style so took me upon receiving it, I decided to keep it for myself! The jewelry box is small, but it holds a lot with a double-layer structure that provides ample storage space for various types of jewelry. It easily accommodates rings, necklaces, and other small accessories without clutter. One of the highlights of this product is its portability. Its compact size makes it an ideal travel companion. I've taken it on several trips, and it has proven incredibly convenient. It keeps all my jewelry neatly organized and easy to find, eliminating the hassle of untangling necklaces or searching for a matching earring.

I didn’t receive the item and I let Amazon know the item was not delivered. Apparently, they don’t care to follow up with my lost order. Hummm, I wonder how the owner of Amazon would solve this problem.
