Update:
I'm going to leave this post up, but I would recommend AGAINST using my files for this mod. Instead use the github project below that is more complete.
---------------
Now that the RC1 Stealthburner has been released I remixed from the posted CAD file to extend the ducts 8.3mm lower to accommodate the offset from changing the Phaetus Rapido over to the UHF configuration with a volcano style nozzle.
Note that utilizing this mod will require some modifications to any inductive probes or the klicky mod. I do plan to remix the klicky mod to extend it to be compatible with the UHF Rapido and will post that once ready.
This is a remix from the official RC1 CAD files posted on the Voron github.
