A simple charging station for multiple devices with different variations. There are models for 5 or 7 devices, with closed or open bottoms.
I personally printed the 7 devices with open bottom to use at home with a 5 devices charger tucked under it, careful consideration of the print material has to be taken into account if you're putting a charger under the station, chargers can get very hot and PLA will warp over time (I have reprinted it in PETG and so far it's been fine).
If the dimentions below aren't right for your devices, you can always scale the model in your slicer to adapt it.
Dimentions ;
5 devices ;105mm by 120mm
7 devices ;145mm bt 120mm
