Well, hold on a minute.
I think it is possible to recover in this particular case.
You don't say if the blank is wood or acrylic. I will assume it is wood.
All you have to do is turn a dowel down to size of 12.5 mm and glue it into your oversize hole. Let the glue dry and cure. Then drill to the correct size
If it is an acrylic blank then make the dowel out of the exact same acrylic blank.
Mal, of course it has to be a hybrid.... Pinecone with acrylic. I do like your idea of turning a dowel then inserting that. Why does the material matter? It is for a Zen kit, the bushing size is .512 which is basically 13mm, so my 12.5mm hole theoretically leaves me with .5mm. is that enough?

This will work as long as the final OD is large enough to not turn down to the dowel, unless my thinking is flawed (for the wood). For the acrylic, why use an exact acrylic blank as an insert to repair another blank? Just use the new blank? (Not to be critical, just pondering the suggestions).

That 0.5mm is divided by 2. You would only have 0.25mm (1/100") thick material if you re-drilled perfectly in the middle of the dowel. You could add spacers on each end so that the recovered blank is in a thicker section of the pen body.
You might could recast the hole with matching color (good luck) resin and drill again.
Looks like you have some good cap material for a Jr. series pen.
