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.

Nice formal European look suit for kids
Color: Dusty Blue, Size: 12
Very nice suit with a European look. Comes with a jacket, double breasted vest, pants, and tie. Does not have a shirt. The jacket is very well made and has sleeve buttons for a finished look. The vest is double breasted for the formal style of the suit. The pants are hemmed at the bottom, have an adjustable waistband, and belt loops. Very well made from quality materials. Fits as expected. Great style. Coloring is consistent between the jacket, pants, and vest. The buttons are durable. Highly recommend this suit for your kid.
