The Classic 2 has the very same form and ergonomics as the unique however gives improved connectivity, a extra correct and dependable scroll wheel, and an upgraded design, making it simpler to 3D print with out the necessity for including help supplies.
The most helpful enchancment on the Classic 2 is a swap from USB-B – that chunky USB port most frequently discovered on printers – to USB-C. The firm initially went with USB-B as a result of it discovered the connector to be “very mechanically robust,” however has since discovered USB-C to be simply as dependable after utilizing it on different merchandise.
