Been busy...

I think HDPE would be a great low cost material for a gel box.

How about roto molding it thick instead of vac forming? For roto molding,
you get the plastic hot and runny, and the mold might need to be not too cold
that freezing happens on contact, then you rotate to get an even film
while cooling down, then open the mold.

I have not done this. It's a known technique though.

Probably better would be a 3DP that uses plastic granules instead of filament
and uses HDPE to get a near net shape, then mill it. You get to recycle the
milling chips.

OK, back to your reality of DIYness... get a cord clamp.
It will tighten onto a thin wall like a milk jug, and
seal a feed-through ( the graphite), also.
