Hotend testing framework

A project log for Multi-Material Hotend

Based on my experiences with the Multi-Material hotend for the Prusa, I'm trying to build something "better"

With the AnyCubic's Kossel assembled, I'm replacing the standard hotend assembly with a 3d printed carrier designed to accept the high-temp resin hotend. You can see the frame here:

The hotend will slot into place and be secure with the fan bolts. I modified the hotend wiring to make it modular, using a 5.5mm jack for the heater power, and a smaller 6-pin connector for fans and thermistor. That makes is really easy to pop out the regular Kossel hotend assembly and replace it with my experimental ones.

The new carrier was printed with Rigid Ink ASA and then the 6 rod attachment points were threaded using a standard M3 tap. It's not as rigid as the standard part, but I think will be good enough for these tests.
