What can I use to block edge pro?

[Volgore]

what can I use to block the edge pro so it will sit in it's proper position without having to tighten/losen the screws alot.

There is a shelf underneath the edge pro, what could I stick in there to keep the trem from caving in?

Anything that essentially fits into the cavity..

Most people use wood

Although in cases of dire need I've used...

Coins, Picks, 9-volt battery, broken pieces of chopsticks, etc..
