Battery case for Aneng ST180 multimeter

A case for batterys for Aneng ST180 multimeter when I leave my cheap batterys in my cheap multimeter they go to zero real quick, so I made this to put them in and for spare pares too. can hold 4 batterys AAA with a lot of space, so it will move easily the lid uses slide mechanism (i think) I did about 0.4 clearance because I like it to be very smooth, if you want it to be tighter make it yourself it is easy Used super glue to attach it and it was fine it is my first time sharing a work mine, and I am also new to 3d printing and designing, also i am lazy so sorry :)
