Dragon Burner v8 Ender 3 Hotend Mount

This model makes the Ender 3 hotend compatible with the Dragon Burner toolhead by Chirpy2605. 

My hotend uses a Copperhead heat break from slice engineering, which adds 1 mm to the length of the hotend. So i have made in total four versions of this model, one for the stock Ender 3 hotend, one that takes my added length into account (simply mounts the hotend 1 mm higher) and pre-supported versions of both.

The model uses two heat set inserts and two 2 M3 BHCS. The ideal length for the BHCS would be 19mm, but i have gotten away with 16mm and if the backside of the Dragon Burner is not flush against it's mount, e.g. my mount for the Ender 3 (https://www.printables.com/model/1389014-dragon-burner-v8-ender-3-plate-adapter), 20mm should also be fine. I am also fairly certain that SHCS type bolts would also be fine, but they would protrude slightly out of the model.

The model should be printed according to the Voron print settings(https://docs.vorondesign.com/sourcing.html#print-settings). The model file is oriented correctly and i have included a pre-supported version, but this is my first attempt at premade supports, so i am not certain that they are better than slicer generated supports.

So far i have only printed the non supported version which fits the dragon burner well. The heat set insert holes are slightly short, so you shouldn't push the inserts in too much. You might also have some material overflow and block the side of the insert that would face the hotend, but simply screwing in a bolt from the clean side would remove this.

Once i have mounted the hotend and tried printing with it, i will include more of my experience with this model.
