Two ideas for next time
Do as you did before but really beef up the side flanges and when finished remove all the loose flanges then use gravity/inerta to get the part out
Hard bash on one end of the flange while holding the other end should see your pattern flying out
Lots of shock isn't good for your gelcoat but will be ok for a one off home brew
Or drill 2 6/8mm holes through the top of your pattern (long as you don't mind destroying it) countersink them so when you bolt a countersunk bolt in its below the surface
Fill and polish on top of the bolt heads and you now have 2 studs coming out of the back of your pattern to strip out with
