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.
