Here is my full submission. Again, I'm not an artist, so I used my skills to provide something visual.

Nice...Just one minor complaint....
"Unless otherwise specified units are in
inches"..... boooo!...
Oh snap! Inches are for carpenters... lol
Thankfully, I work in probably one of the few shops in USA that actually works in 100% metric .
(like most of the rest of the world.)
All solid models, drawings,cnc programs/feed rates and measurements/tolerances are in millimeters, so no silly 25.4 converting. I think in metric.
I have worked in both units and can say unequivocally that when it comes to machining precision metal parts.... metric is sooooo much better.
As units are smaller it takes less information to represent same accuracy. (1mm = .0394 inches)
...But besides that...great job.
Btw,if you can post an engraving g code file(metric of course lol) I can try milling it for you.
