#Main Body This remix comes because I like the original model but it doesn't fit the cooling ducts of the hero me v4. Here the modifcations I made: 1. cut a notch for the screws holes to make the screw heads flush (stock screws should work as well). 2. reduced the slots to use standard nuts (not nylon lock-nuts) 3. adapted the mounting holes to fit herome fan ducts v4 (v5 shoudl be compatible but I've not test it yet). 4. removed texts on the body 5. added some outlet holes on the side, it should help the hotend fan to push out the hot air from the heatsink. 6. reduced tollelances between the body and the heatsink to improve heat dissipation. 7. added a notch on the mounting screw, this can be used to accessories like bl touch, dial gauges ... . #Accessories + *Dial_indicator_holder.stl* It allows to fit a dial indicator (mod. n7) to check bed level. Tested wit a 3d printed version : https://www.thingiverse.com/thing:4524389 . + *Top_wire_mng.stl* It should be mounted on the riight side of the BMG extruder, it provides a way to fix all the wire from the back of the printer to the hotend. Use 2 cable-ties through the holes to secure the wires. #Changelog **2021-03-31 - V2 released** The V2 has been published, the main changes are on the cooling of the hot-end. It reduces the tollerances between the body and the heatsink and adds 3 extaust holes on the left side to expel hot air. **2021-01-21 - V1** Published first model of the body.
