You do not have to download any of these STLs and print them yourselves to complete the conversion. The stock fan duct of the Ender 3 will fit our carriage by default. Only print these if you need to install auto bed leveling sensors such as the BLtouch or KAVA lite sensor.
1) If you have the KAVA lite sensor, this is the file you need to attach it to KAYD3D's CoreXY hotend plate
2) If you have the BLtouch sensor, this is the file you need to attach it to KAYD3D's CoreXY hotend plate
Disclaimer: All STLs are tested on the actual machines. Please let us know if we have uploaded the wrong STL files.
You will need also probe offset values when you have an auto bed leveling sensor. Ignore this part if you don't have a sensor installed.
Please use these probe offset values as guidelines. They may be slightly different from yours.
X: -42, Y: -11 = Ender 3/ Cr-10/ Creality Mk 8 hotend + Original fan duct + KAVA Lite Sensor
X: -40, Y: -12.5 = Ender 3/ Cr-10/ Creality Mk 8 hotend + Original fan duct + BLtouch
Print them in the following orientation. Supports may be required.
