Nice! I think I am going to print a set out for Powerbook tonight.
Thanks - I meant to make one improvement today - I’ve realised (by looking at a removed top case) that the pointy end should have a fairly long tag on it to engage with the case (as your design does). All mine were broken off, so I put on a clip the same as the other two clips.
The two side clips are fine but the end clip isn’t quite correct - it doesn’t hold the cover as tightly as it should. It’s OK when assembled, as the screen housing won’t let it move far, and it’s easier to get in and out, but I’ll be adding the correct version soon (eight hours from now).
AEChadwick - sorry for this small mistake but I’m glad you’ve pieced your ultimate-Blackbird together - looks great
