Drilled a few holes in a Pluggis box with lid, and added flowers on top.
1) Drill out the holes in the Pluggis box
2) Cut out the EVA foam, cut holes for USB cables, and then staple on the flower patches
3) Pull the USB cables through the holes in the foam and lid
4) Put the USB multi-charger inside the Pluggis box and attach the cables
5) Set up your new charger box
