That would take forever. ?A homebuilt vacuforming rig could bang out dozens

Indeed. We have a 2'x3' sign-making vacuformer at our hackerspace. I
think the stock on hand is colored polystyrene - rather thin, but it
conforms well. I was thinking about making a form out of 6mm
hardboard. The thing that will take the longest is drilling lots of
tiny holes in the base to get a good pull.
One thought is to make a form that has no base and looks a little like this...
TTTTTT
Where the backstop is one piece as wide as necessary (probably around
8") and each "leaf" is long enough to hold a stack of fanfold tape
with some protective gap (around 10" IIRC). That would take a few
minutes to cobble up.
There's room on the table for at least 4 of these in one pull (you
have to do a full sheet at a time or the vacuum doesn't work - it's a
simple machine with no way to block or divert the air for a partial
sheet, or to clamp a partial sheet in the carriage)
