I liked the honeycomb desing from the remix on Thingiverse, but i wanted to use M3 screws. They are like 1mm out of the side walls because the walls are 3mm thic
 

The differences with the remix design are:

• Smaller screw holes to fit M3 screws.
• Handle removed from the model.

You will need to print:

• 1x Rightside
• 1x Leftside
• 4x Backholder
• 4x Frontholder
• 1x Top Backholder
