Homebrew PCBs

I wouldn't use cyanoacrylate, either. If you can cut and sand the
pieces to fit very tightly together, solvent welding is the way to go.

Degrease before sanding! Otherwise the grease ends up in the sanded
scratches and can be very difficult to get out.

Plexi might be difficult to heat weld. It has a pretty narrow heat
band between where it softens to welding temp and where it starts to
bubble.

If you bend some of the pieces to shape, make sure they have no stress
in them. Plexi is very brittle and prone to fracture when solvent glue
is applied if there are -any- stresses. And prone to fracture slowly
over time from those stresses. I had a plexi case I made slowly crack
all the way across two of the bends over the course of a few months.

Please post pictures in the Files Section. I don't like the Photos
section because it resizes the pictures, if you upload larger only the
moderator and the person who posted them can see the full size version.
