rpi zero 2w base plate with or without 30mm fan

after not being able to find simple base i came up with this design simple base to cover bottom of pi zero two versions are avalible one with 30mm fan and one without 

requires m2.5 nylon screws and nuts holes may need to be drilled out depending on printer to slightly larger 2.5mm drill bit will do 

step files are included if wish to make modifications
