How to Make a Custom
I need some switch panels for the overhead going into
my truck, I used my usual methodology, although this is a car
part, you can pretty much make up anything you need, within
reason, this way:
Draw the parts
in CAD and print at 100% size (my pattern sets are saved as
100%-sized *.jpg files, by the way) on paper. I decided
that square panels were boring, so I got kinda artsy-fartsy
with the mount tabs.
Then I used some blue masking tape to cover my 6mm PVC
scrap (I got this material just for begging a dumpster-dive
, and it is a dead-on match for vicky
red, coincidentally) and then sprayed the back of my printout
with Super90 Spray Adhesive.
Note that I didn't spray the masking
tape- because any areas not the covered by paper would then
stick to my fingers and make cutting a pain instead of a joy.
(It's fun making your own stuff, when it doesn't include

CAD artwork after cutting. You could also use cheap contac
paper to do this, and I have had very good results with it.
the hole locations in advance with a punch or similar item.
Drill bits walk around without a center
mark, even on a paper surface. Also, start with a tiny drill
bit, and 'pilot' all the holes first. Any error in drilling
will be MUCH smaller with a small diameter bit to start. Then
you can enlarge the holes later with a bigger bit, and it
won't wander. That way, all the holes will line up.

panel, minus sanding. The front row of switches is
test-installed at the moment. The other 16 switch positions
will have standard, un-shielded toggles. Maybe...
I like "Helicopter switches" a lot, and
