Thanks a lot for your reply.
So new version:
I've corrected the pinholes diameters. Now a pin can fit (there is one within the file).
Then, to know what could be the Z position: do you think that this part should be "clippable" on a 1x16 technic brick for example? If yes, I can move all the pins to fulfill this condition.
Another thing that can help: do you think I should use only 0 digit values for the Z position.
As an example: something like "from 0 to 16", and not like "from 0.5 to 16.5".
