Do some 3D Modelling

This project is really a correction of a previous one. My first rendition of the model didn\\\'t function, (please see attached file) i.e. the star pegs did NOT fit into the star holes & round pegs don\\\'t fit into the round holes. I\\\'m pretty sure the pegs just need to be smaller than the holes (lol). It should be fairly straightforward. I also would like to change the formation of the letters. If you view my already made rendition, and see what I\\\'m talking about, and see that this sort of thing is up your alley then let\\\'s work together! Thank you.
