Formbot/Vivedino T Rex 3.0 E3D V6 Hot End Upgrade

thingiverse

This is designed to replace the stock hot end mount for an E3D V6 hotend directly. The stock hot end included with the T Rex 3.0 cannot handle temperatures above 250 degrees, resulting in PTFE tube breakdown and jamming issues. While a metal heat break swap might be sufficient, this upgrade is intended for those who want to replace the entire stock hot end assembly with genuine E3D parts. You will need (for each side): (4) M3 bolts that are 8 mm long for mounting the adapter to the stepper motor (2) M3 bolts reused from the stock mount Note: The adapters add an extra 5 mm to the distance between the nozzles and the x-axis, so you can either edit the Marlin firmware or just change your print size to 390 mm in the y-direction to offset this. The E3D heat sink fan must be on the opposite (short side) side from the stock fan. Ensure there is at least 26 mm between both extruders when printing in mirrored mode to prevent them from colliding. Version 2: Modified the adapter so that the E3D fan fits right side up.
