Summary

Just print it ,cut acrylic 4 mm and put it together.
It is a simple idea but I believe you will find it useful.
Using tinkercad you can customize it at your needs
For the top cover I cut it 0,1 mm longer and I put it without any other support or screws.
Cut & plug it.
To cut and engrave acrylic I used a co2 40 Watt laser.
