It's a newly designed hotend mount for the EVA 3.0 / E34M1 system. The version available here on printables allows the airflow from the hotend fan going to the nozzle. That can cause fine hairs on prints (stringing). I want to block that flow and designed a new mount.
It comes in 2 versions: one for short screws to mount it on the toolhead and one version for long screws.
You need a good bridge setting in the slicer. The model is designed for printing without supports.
I printed it with ABS:
5 walls
5 top/bottom layers
55% infill
Use 0.2mm layer height to benefit from the built in supports!
The author remixed this model.
Another hotend mount for the V6 TZ2.0. Designed from scratch with the hotend-template available on github.
