About this 3D model

My wife loves Sudoku , I found KobaRilys Sudoku Board and tiles on Makerworld, https://makerworld.com/en/u/3207121644, she loved it ! . Its a great model I heartily suggest you print it if you are a Sudoku fan. She only had one complaint, when she would move the base or take it with on a trip the pieces would fall out. She asked if I woulld make a case for her. Its simple and works well print on its back and there is no need for supports. I hold it to the base with a simple paper clip. Print Settings Material: PLA or PLA+ Layer height: 0.2 mm Perimeters: 3) Top layers: 4 layers Infill: 15% lightning Supports: no
