If your not familiar with pi-hole heres the link. https://pi-hole.net/ This is a case for pi-hole using pi-zero w. First file is for reference only. It is not a print in place file. The slide in lid looks really good when adaptive layers in cura is used. It gives the top layer a smoother finish.
update 3/3: added friction fit model. The file labeled piholetop7 is what worked for me. It has a .2 tighter tolerance all the way around.
