Hi PaQ,

>Is it any part that was more complex to build than an other ?

Funny you should ask because the parts A and B that you want a close up of were probably the parts that took the longest time to process, what I mean is that once I executed the Boolean operation I went away, had a coffee and a chat with the wife then come back and do the next Boolean operation.
You will notice with the scriber that there is a fault because I couldn't get the last Boolean to work so there is one twist missing, but for this project I wasn't too fussed.

The trick is with this kind of knurl pattern is to make the crossing Booleans a slightly smaller diameter, it'll will seem that MoI has hung but be patient it will do it, there is some serious number crunching going on there, you'll see what I mean from the close ups.


Cheers
