I wanted to make a plate stop/aligner for normal ender 3 build plates to be used with the K1. I don't have any ABS atm though, so I can't test it. If anyone wants to beta test it please give me your feed back.
To install it you should be able to unscrew the screws that align the original plate and then screw them back in upside down through this part.
The author marked this model as their own original creation.
