This is a remixed fan duct model that accommodates the larger size of the Creality spider hotend as well as a small change to the autobed leveling attachment piece. The original model seems to work well with a CRtouch but seems to be missing some distance to read the bed correctly.
Updates to this model
You can print out all models with no supports.
The backplate has built in supports for the bltouch attachment. I did this to save on time and material. You will need to bridge so make sure your fan speeds are up to 100% on the bridging.
