About this 3D model

This is simple and functional, fully 3D printed, ice lock. It works in simple way: 1. assembly it like on photoB and put ice cube inside, 2. put cover on top (photoC). In this moment lock is secured and can be opened only after ice fully melts. Cover prevents you from removing ice - it has latches and can be prinsed from inside (with screwdriver or somehing thin, like pen). Of course it's just plastic - but it's strong enought to give a lot of fun ;) Eccelent for dropping keys or something like that. (if you want to use it in this way - inner part should be mounted permanently and keys shound fall down with larger part because it's heavier). Project is created for max 30x30x30mm cube. With 30x30x23mm cube and room temperature 24°C, it takes about 2h to open! There is no additional parts - just print those 3 details and you'll have fully functional ice lock. Use it safely ;P
