CASE For MiniWare ES15

I want to make a case for my miniware ES15 i came with this simple design with minimum hardwares and its can be printed with 180mm bed.there is alot of options there ! but i have 3d printer to make it and same time to be stackable with my other boxes.the case uses buttons magnet for closing the case to make it easier to print for every printers tolerances and have more wiggle room for non 100% tuned printers .If you can't get it 100% right Make it adjustable ! Needs for mounting 8x buttons M
