THE T 500 IS A FANTASTIC MACHINE BUT THE HOT END AND EXTRUDER UNFORTUNATLY ARE JUNK AND HARD TO GET PARTS FOR.

THIS IS AN ALTERNATE HEAD YOU CAN PRINT YOURSELF. IT UTILIZES PARTS COMMONLY FOUND ON AMAZON. I'LL LIST THEM BELOW.

V10 ALLOWS YOU TO USE ANY OF 3 EXTRUDERS. THEY ARE LISTED BELOW BUT ALL ARE EXCELLENT FOR PRINTING TPU AT HIGHER SPEEDS. YOU CANNOT USE THE ORIGINAL EXTRUDER MOTOR FROM COMGROW SINCE IT HAS A 8 TOOTH GEAR AND THESE ALL REQUIRE 10 TOOTH.

I LIST A GREAT HOT END BELOW THAT IS A KNOCK OFF OF THE BAMBU LABS HI FLOW HOT END, BUT YOU CAN USE ANY HOT END THAT WILL WORK ON AN ENDER 3.

ANOTHER FEATURE IS SIMPLICITY IN MAINTENANCE AND REPAIR. TWO SCREWS TO REMOVE THE FAN SHROUD. TWO SCREWS TO REMOVE THE HOT END AND TWO SCREWS TO REMOVE THE EXTRUDER.

YOU CAN REUSE A LOT OF THE HARDWARE ON THE ORIGINAL HEAD. YOU WILL NEED TO EXTEND THE WIRES FOR THE FANS AND SOLDER CHANGE THE CONNECTOR ON THE EXTRUDER MOTOR. IVE LINKED A KIT IN THE PARTS LIST BUT YOU'LL HAVE TO SOLDER.

YOU WILL ALSO NEED AN ASSORTMENT OF M3 SCREWS
