Hero Me Gen5 Master Suite
Welcome and thank you for considering the Hero Me Gen5 cooling system. The Hero Me Gen5 is a major upgrade to what is considered by many as the best cooling system for  Creality 3D printers. The Hero Me has a dozen YouTube reviews, hundreds of public endorsements, as well as Hero Me Gen5 screw & nut kits coming from PrinterMods.com.
A detailed and illustrated PDF with all the assembly instructions and parts cross reference is included (it is the first file in the Downloads section). It will guide you in selecting the parts needed for your printer as well as walk you step by step you through printing, assembly, and setup to be able to make great things with the Hero Me Gen5 and your 3D printer. There is also a folder organized ZIP file you can download that contains all the parts and documentation. It is the last file in the Download section.
Here is a couple of great assembly and testing videos from the YouMakeTech YouTube channel:https://www.youtube.com/channel/UCmCW2lJ6Q0-xc1VtKxdK9MQ…
