I realise casting resin isnt a thermal plastic, but I seem to recall some thin resin casts can be heated gently so they slightly soften up and can then be slightly pushed or manipulated?
H have a little issue where many of my castings have slightly warped, not sure how or at what stage in the design. But a simple fix would be to heat some flaps/wings and ease then back a little so they can fit again...

Is that possible here?
