Anet A2 – Modular A Carriage System The design is an upgrade to the standard Anet A2 carriage with the ability to quickly change hotends. This new design has the same mass as the original, but includes all-new features. Key Features: internal structures for added stiffness, embedded metal mounting nuts, screw heads for wheels, side brackets for tools like auto level sensors, belt tensioners, electrical connector mounts, cable chain mounts on the back, and V-Slot hotend mounts. The V-Slot brackets are designed for Bowden systems. The design is intended to keep mass low for higher speeds and precision while allowing quick hotend changes. It's recommended to use an M4 thread tool in the cable chain mounting hole, press M4 nuts into place with a tool, and pull M3 nuts into position using a screw and washer. Heating up the carriage before pressing and pulling is advised. Corner brackets and level sensor mounts can be found here: https://www.thingiverse.com/thing:3139074 Anet A2 hotends are plug-and-play compatible with this bracket. E3D V6 fan systems have been redesigned to use a single 3010 fan for cooling the E3D V6 and dust prevention. Find the dust and fan protector design for the E3D V6 here: https://www.thingiverse.com/thing:3133238 The V-Slot brackets are designed to allow for minimal bed adjustment during hotend swaps.
