Hi guys I’m selling a custom aluminum bed plate made for an Anycubic Kobra 3 Max upgrade project. The plate was designed in CAD (3D file available), cut from a 0.8 mm aluminum sheet, and then surface ground. The results were really good (bed mesh range around 0.3 mm, see photos), but I decided to switch to a different printer. It’s ready to use. I’m happy to help with the installation step by step and I guarantee a good first layer once mounted. Feel free to DM me for details, dimensions, and price

Professional CAD project for an aluminum bed plate designed for the Anycubic Kobra 3 Max.This is the actual file used to manufacture a real aluminum plate, installed under the heated bed to improve flatness, rigidity, and overall bed stability.

The design can also be used to rebuild a complete bed assembly or as a structural base for custom solutions mounted on top of the bed (glass, PEI sheets, magnetic systems, or other upgrades).

Files included:– STEP file for full parametric editing– DXF file ready for CNC / laser / waterjet cutting

This is not a theoretical model: it is a tested, real-world project, intended for advanced makers, CNC services, and serious 3D printer upgrades.

The CAD model precisely matches the original heated bed mounting hole pattern of the Anycubic Kobra 3 Max.Hole positions were taken from the real machine and verified during installation, ensuring full compatibility with the stock heated bed and existing hardware, with no modifications required
