Box for Pads

On Thingiverse I saw a contest to make something for in the kitchen.  This is my idea.  A pad holder to put on the wall.  The first part, the box, is ready.  It has printed 11:20 hours.  It is 5.75 cm height and 8.3 cm wide.  On the first image you see the support material that is being made for the opening in the bottom of the box.

The idea is to get the pads on the bottomside out the box.

The print came out quite good. The pads fit in the box.  In Blender I created a pad as a mesh object. This way I could  visualize how the box will work.

But the box had a problem why I can't use it. I forgot to visualize also my fingers.... The opening on the bottomside is to small or my fingers are to big..

I visualized it in Blender by taking the measurement of my finger and tumb. This way I could have seen it clearly from the start.
