Nutone Battery Cover

my parents asked me to make them a new battery cover for there really old Nutone LA-99R door chime. my dad accidently through it away when they moved in. so i drew up a quick sketch and printed it out in pla. it turned out really well for the first try, im later going to extend the front clips by .5mm. they hold really well but just for my own satisfaction i want to do it. i hope you enjoy.
