DM Dice Tower

My first 3D model which i made using Tinker cad. 100% scale should be just big enough for a single die to pass through it but I would suggest 140% scale as i believe it's the best size when rolling a few dice at a time. I personally think the best way to print this model would be right side up as the only support needed would be over the exit hole and would be easier to remove than any other orientation. Let me know what you think of it and if you have any recommendations as this is my first mod
