The xTool RA3 MagSwap™ rotary attachment allows you to engrave a wide variety of cylindrical objects such as cups, rings, vases, glasses, bottles, and much more.
The improved plug-in system lets you reconfigure the rotary attachment within seconds so it perfectly fits your application. Unlike previous rotary extensions, the RA3 not only enables you to clamp larger-diameter workpieces but also allows you to engrave objects like vases all around.
Optional Mass Production
Optionally, you can purchase multiple xTool rotary attachments and connect them in sequence to engrave several candle jars or similar items simultaneously—ideal for batch production.
The RA3 offers the following modes and diameter ranges:
Roller Mode (3–198 mm diameter)

- Can be combined with multiple rollers for mass production
Chuck Mode (0–130 mm diameter)

The Makeblock success story began in 2012 when Jasen Wang, the founder and CEO, had a groundbreaking idea. As a passionate maker, Jasen realised how difficult it can be to turn a creative idea into reality. This drive gave rise to his first project: Makeblock.
Makeblock specialises in promoting STEAM education. The company helps young students develop their creativity by developing educational infrastructure - including robotics modules, coding software and laser cutters. The aim is to give pupils the tools to learn technical knowledge and creative skills through play.
At the end of 2020, Makeblock expanded its portfolio and entered the field of laser machines. With the xTool project, the product range was expanded so that not only students but also adults can benefit from the solutions. Creativity is not just about developing programming robots - it is also about personalising everyday objects, such as engraving names on mugs or creating works of art from wood.
With the launch of the first product, the xTool D1 in 2021, Jasen started a new chapter in his vision. While the Makeblock success story continues, xTool marks the start of an exciting new episode.
