Made a version that is easy to stack and do not have any sticking out. instead I made holes and some clip that also could be printed.
I started with the Prusa model, but finally I made a new one instead. The rubber band could be adjusted and fitted without any holes and the type of rubber band is more variable from what you could get hold of.
Shield mount is printed 0.3 layer height 3 perimeter, 2 bottom and 3 top 0% infill.
Clip is printed 4x4x4 100% infill and 0.2 layer height
Cover on top is optional and could also be clipped with same clip. just print at any perimeter/shell you want.
Update!!
I added a V2 with a better cover and ventilation
