SPICE repair problem

[PANAMATIK]

There are two common repair problems with SPICE calculators like HP-33C/HP-34C

If you try to insert todays AA Batteries or NiMh accus, the case will break at the weakest place, which can be seen here, because the AA NiMh accus are slightly longer than older NiCd accus. I tried to fix it with a 2mm x 10mm plastic sheet strip and Epoxy glue at the inner rim, but without success. How can you fix this problem?



For another reason sometimes one (or both) of the screw holes are broken. I tried to add lots of epoxy and drill a new hole there, but without success. How can you fix this second problem?
