Container for

Hello.
I came up with the idea of creating a container for captured minerals - bought :-). I divided the designed product into places with a movable frame. Dimensions 40, 50, 60, 25mm and others - any choice. The upper part lined with plexiglass (I temporarily do not have). Therefore, I supply the folder with the entire top wall. On the outer walls space for 10mm neodymium magnets. I also thought of handles (without exaggeration :-) I think that everyone will be able to separate the surface. The top part is finished with wedges. I haven't added the wedges yet. I will probably still have to do modification. The created box can also be a storage compartment for other products - screws, nuts, elecronical elements, batteries. I make available.
