Voron Stealthburner for Biqu Nebula

Comments and suggestions are welcome. It's installed and tested on my Switchwire.

I ordered a Biqui Nebula extruder. I remixed the Strealthburner version from Biqu and removed the Filametrix parts. The back fits a BTT EBB36 as per their design (without backplate or spacer). Unfortunately the heatsets will mess up your outer wall, because Biqu designed them too close to the outer walls.

General

I also ordered a Fysetc H36 Combo so I also made a mount plate and a spacer for that. The mount plate has a strain relief for the Fysetc CAN cable. If you use the back plate, use the middle heatset / screw hole at the top, this won't mess up the outer wall. The spacer uses the other holes. The cover is untested, because I havent't wired it up. I printed all the parts and everything fits nicely.

I have already changed the cable routing and added a new channel into the back for the hotend cables. I have enlarged the hole for the PTFE tube so that the tube goes all the way to the extruder (not sure why Biqu didn't do that).

Variants:

BTT EBB36 gen2:

This is only for gen2 as BTT modeled it. It's not eben available right now… I might make a backplate for the v1.2 if there is interest in it.

Print Settings

Use the standard Voron print settings (ABS or ASA). Only the extruder body needs some tree support for the cable pass throughs and some small overhangs.
