It came as a total surprise to me how tough the cured clear resin turned out to be. On prior experiences I’ve had with two-part clear resins, often there was a time when it’d be possible to add a metal screw eye to a charm or ornament., and allow it to then finish the curing process.
I seem to have a Goldilocks dilemma - I don’t want to manhandle and scar the charms while they’re not fully cured, but, I wasn’t able to easily pierce the resin with the screw-eye once it was fully cured. Does anyone have suggestions as to a ‘sweet spot’ timing wise in the curing process when things might be malleable enough? Or, should I simply plan on trying to include a tiny hole where I want the screw-eye to eventually go into the resin, and just treat it as a glued-in-place pin? (I have the feeling that the Formlabs resin isn’t quite strong enough to create a small loop and have it not break off on a charm bracelet during normal movement)
