V 1.1 update I have enlarged the hold for the housing so that the motor works better and have made the screw holds bigger for ease of assembly

this is a work in progress for a completely opens source water pump that can be made with minimal parts ordered from the Bambu labs official store.   I would love to see what people come up with 

in the description I have added the parts I have used to make this for the screw place the silver ones inside the device where the motor comes out and the black ones go on the outside

I have remixed this by making it smaller adding screw holed and making the whole thing work on Bambu labs store parts
