After the lugs have set up (at least 12-24 hours), you can remove the moulds. I found that snapping off the alignment tabs was necessary, and that in most cases some mild persuasion with a hammer and chisel was required to free the parts. Working the chisel in between the gap on alternating corners works well.

While I had realistically only designed the moulds for 1-time use, almost all of them survived the demoulding process reasonably intact (except for the tabs) with the exception of the bottom bracket moulds.
