I don't know what elmers glue is, and I don't have an HP41C or HP200LX. If
the case is plastic, it's most likely some grade of ABS or just possibly
PVC. (If it's a "waxy" plastic it may be some relative of polythene or
high density polypropylene and almost nothing glues those -- you have to
heat weld them.)
Proper ABS cement (available for plastic plumbing) is about the strongest
glue you can get for that, much stronger than superglue on ABS. It doesn't
just adhere, it welds the plastic. An alternative is methyl ethyl ketone,
MEK, commonly available as a solvent and widely used industrially to
glue/weld both PVC and ABS.
Whatever you do, try it on the inside first, where it won't show if it goes
wrong!
