My question is regarding “DROK DC 4.5-100V Digital Voltmeter Ammeter Multimeter Panel” (B07QVXXGVR).
The “<span class=”askExpanderContainer noScriptNotDisplayExpander askExpanderExpanded”><span class=”askLongText”>68mmx37.5mm </span></span>” measurement mentioned on the Amazon website doesn’t seem accurate, it is nearly the dimension of the outer part of the panel.
I’m trying to design a cutout for a laser-cut metal sheet. Can you give a more precise measurement of the proper opening? It seems to me that the best opening would not be a simple rectangle as should allow the “lip” on the front to cover more solid surface instead of the hole.
