The Hemera (formerly Hermes) is a new all in one extruder/stepper/hot end by E3d. I have had a lot of requests to make an install video for an Ender 3, so I present this complete guide.

There are many steps and I’m not sure it’s worth it on a smaller printer like this. Although the initial performance tests are good, I’m going to move these parts to something like the CR-10 Max. The Hemera in isolation is a beautifully engineered piece of kit and will thrive on a printer designed for it from the ground up.

More info on the engineering: https://e3d-online.com/blog/2019/11/2...

Thanks to all of those in the community who have designed parts for this kit.

Purchase the Hemera (please check voltage and filament diameter options):

1:11 Overview of Hemera

2:49 Step 1: Assemble Hemera off printer

4:28 Step 2: Select and print mounting adaptor parts - these are the parts I selected for this video:
Remixed Hemera adaptor by Menissalt (parts A and B, also for BLtouch mount if needed): https://www.thingiverse.com/thing:406...
5015 blower fan duct by Hangtight (duct mount plate and duct parts): https://www.thingiverse.com/thing:404...
E3D hemera Mount and cooler by Tragical (4010 to 5015 adaptor part for stock parting cooling fan): https://www.thingiverse.com/thing:406...

Other parts not used:
E3D Hemera Thingiverse adaptor (A and B parts too thin, 4010 fan duct too low): https://www.thingiverse.com/thing:400...
Hemera mount to suit BLtouch and EZABL by Joe Casha (easy to fit, simple design but I found this wobbly): https://www.myminifactory.com/object/...
