DrillandFile Hot End
Making your own hotend is like baking your own bread - there might be professionals out there who can bake better and have superior gadgets to do so, but nothing compares to your own, self-made bread.
This hotend is just another attempt at designing a simple hotend which can be made DIY-style without the need for expensive tools, machinery and materials. It was inspired by the Watson_Hot_End, the KISS_Hot_End and the Wildseyed_Simple_Hot_End.

The current version is v3 and works quite well. Besides printing calibration pieces and robotics parts, I have used it to print all parts for my Mendel90.
Example Prints
First, some examples of prints made with v2 and v3 with a 0.5mm nozzle:
