About this 3D model

I've designed this Geocache box with the idea of being magnetic. It can hold up to 4 magnets on little holes at the bottom. The first version was in PLA and stayed outside for a year but lost the magnets and now is missing so I recommend using PETG for this, will hold better under the rain and hot/cold weather.
