After much research, it appears the Ender 3V2 was delivered with 1 of 2 variations of backplates. These are both  Creality Gen2 backplates totally different than previous backplates (ie:CR10). I have adapted the Blockhead Ender3v2 base to accommodate either plate. Dave
I have a new duct optimized for the 5015 with a very small footprint for the Bullseye base. It appears blocky but that shape is just to make it easier to print. The interior is fully CFD optimized. I call it the Bullseye "Blokhead". It is backward compatible with all Bullseye bases.
