Hadn't checked in here in a while, have a board that'll need to get made soon
and this looks good so will have to give it a try. Everything that is easier is
great, you can always fix a little smudging later.

Can't remember which it is off hand that is easier to bend with heat, the
carbonate or acrylic, but find that out again and get the easier one. Make a
rectangular sheet that is your larger 2 sides and bottom all as one piece.
Table saw a 1/4" groove down each longer side, maybe 1/4"-1/2" in and like 1/3
through the sheet, with 1/4" sheet. Two folds to bend up the larger sides, and
the groove will hold the smaller sides, greatly increasing the surface area and
decreasing chance of leaks. Use the welding type glue not silicone, with the
extra surface area you shouldn't have a problem. Might find some other glue
that will stick ok and put a fillet on the outside of the joint, simply as a
physical block to slow any leaks just in case it does spring one. If your slot
is tight to the inserted sides I don't think you'll get any leaks after just the
weld glue anyway though, I've seen joints like this and they are very good.
Keeping the corners a bit rounded is best, make it more of a flat bottom U shape
than right angles and it should be good.
