To get a tidy speaker grill on your EF01 enclosure or what ever you are using have a rummage in the kitchen utensil draw you may find the perfect template.? I used a plastic sifter lid as the holes were the size I wanted.
Draw a center line where you want it positioned, line up the template, drill one hole on the outer circle, insert nut and bolt, drill hole opposite end of template, insert nut and bolt, now drill rest of holes in perfect place.? Hot glue speaker in place on
underside of lid.

Thanks! ?I was look for an easier way to lay out the speaker holes than using a ruler & a pencil with careful measurement! ?I took a dead LCD display, carefully milled out the PCB behind the black metal frame (after removing the LCD's guts) and now use that as a template for milling an LCD window in either PCB, Aluminum or Plastic panels. ?(Have to run the milling bit really slow on plastic or it gets all gummed up though - LOL.)

Might help,
I use a hole saw and drill to cut speaker holes, I picked up my kit from Home Depot it’s made for cutting holes for door knob assemblies. Works best if you have a drill press. For grilles I use metal fan guards, like for pc fans, 80 thru 120 mm depending on speaker size and they are less than a couple bucks. BG Micro has quite a few different sizes.
Since I play with Tube Amps and Radios I have several chassis punches that help with holes for displays and such. I rough out then use nibbler and file.
Maybe this will help someone else,

I used a square of Vero board and drilled pilot holes, then opened them out slightly. Left with a square grid with staggered holes, seems to work well. Need a drop of enamel to finish the bare metalwork off.

I haven't done it myself, but another option would be to print a pattern on paper and tape it to the case and use that for a template for drilling holes. I just came across a suggestion on eham.net to use graph paper for the hole spacing too. I do like your template idea though! -- 73 Keith VE7GDH

Should have said that I print out template in PowerPoint and a fix before drilling and cutting. Use a good center punch to start drill bit with hole saw, lesson learned hard way.

This really worked well. ?I needed something a bit smaller (2" speaker) and I found one that had 3/32" holes in the kitchen so I used that. ?I slipped on one hole in the center so it's slightly off but all-in-all it still looks okay - building this thing should include a cosmetic error or two anyway just to prove you built it and not some factory - LOL!

Really nice, you cabinet
look perfectly sized.
Bezel looks like the ones I 3D print,
makes it look really finished.
How did you do the
decals?? I am still wondering about "water slide decals"
mentioned here?
I have Laser B&W,
no inkjet.?

Yeah, a lid from a giant shaker could be the actual grill, not just the template! I don't think I could get away with cutting the bottom out of the ricer.

Is that a one piece aluminum case? If store bought where did you get it/part number, it looks really clean.

Hi,
as speker grill, I have been using, in some projects, the italian moka coffee espresso spare filters,as the one reported in picture.
These are of different sizes, starting from 2 coffee cups up to 12 cups, as the one in picture. No sound problems.
The filter has a flange and it can be glued to the panel, or blocked by the speaker.
