This is a Work in Progress. Ebb 42 is a great replacement for the extruder breakout board on the sprite extruder by creality. ebb 42 is a lot thicker and with wires hard to place where the original board is on the sprite extruder. My design securely attaches the board to the right side of the sprite extruder and also allows for easily detaching it for repairs. It can work with the original mount on E3S1 but I recommend using a 2020 Gantry plate instead of the default L shaped bracket and using proper printings quick tool changer( https://www.printables.com/model/359377-ender-3-v2-tool-change-system-with-sprite-extruder ) so you don't have to remove the ebb42 board every time you want to take off the extruder.
There is a tab at the bottom which secures the board to the extruder. you have to pull the tab before you can slide the ebb 42 plate off, this helps the board not rattle around and cause problems with input shaper readings.
M3 screws are needed to mount the ebb42 board to the plate. The base was taken from ( https://www.thingiverse.com/thing:5942676 )
If you are using the original L bracket(on ender 3s1) to mount extruder then you can use this design to fill the gap where the breakout board used to be: ( https://www.thingiverse.com/thing:6071170 )
Any feedback will be helpful. Some more refinements can be made and I plan on making a snap on shell to cover the ebb42 board soon.
