12mm D6 storage

Update 7/24: Tolerances were too tight for dice and one end was not sized right anyway. Have widened each slot. Also found that the latch was prone to breaking and modified it to improve it.
Update 7/22: The gate is not printing correctly on some machines due to separation tolerances. I have done a redesign which will separate them into two parts to be assembled. I would really like to get feedback from anyone who tries to print this.
This is for storing a brick of 12mm D6. It should hold 36 that come in the brick.
It has a built in latch. If for some reason you feel that the latch is not good enough there are guides for rubber bands as well.
This is my first completely from scratch item. I am hopeful that it will come out right. I am open to feedback and pointers for improvement
