Does it need to be very solid, or just hold on?
A gentle and removable nice looking option is adhesive coated foam.
You can get tape and pads, different thicknesses, you want both sides
sticky. This is widely used in all sorts of products. It should be
thick enough so you can never compress both adhesive sides together,
or they might rip components off (happened to most Samsung SGH 2400
phones). That's a problem with any strong glue or spacer material, so
the foam is good because it will flex or even rip before that happens.
Hot glue will work for this, I've used it a number of times to stick
stuff right on top of populated circuit boards. But it'll look very
much like a bodge no matter how neat you try to do it. If that don't
matter it's a solution.
