That’s incredible! You sir are something of an expert with Tinkercad! I spent an age before trying to work it out and gave up in the end!!
The part in your design looks pretty darn accurate, aside from the internal angular pieces, but honestly please don’t go to any more trouble though, you’ve all done more than enough.
I havent actually done anything at all - I can give you that model to edit if you like though. Alternatively send me the part and ill 3d scan and print the thing.
