RE:
Yes, print it as-is, it contains a predefined support that you break out before fitting.
Cheerio,

Hi
got it running! It broke out itself… now my Prusa is running with new hot end again.. 6000 hours in 2 1/4 years … what a great machine!

I recommend that you print this at minimum with ABS/ASA, and preferably with something higher temperature, like PC Blend.
The original on mine (I assume ABS) started to droop after a fairly long run of ABS prints, and I found a remixed one (below, left) that looked a bit more sturdy.
I printed both the remixed one and the original (right, below) with PC Blend and made the decision in real time to use the remixed one when I had the machine down for repair. It has not drooped since.
