BLANK WATCH - Designer Wristwatch - any 20mm strap

Hi guys!
It's my designer watch project! BLANK WATCH.

You DON'T need spring bars to attach strap! You just need to cut 25mm of filament! 20mm strap fits into my design :)

Please, give me your feedback!

PS: I used some top layer pattern on my print, it doesn't looks good, but my print profile is using normal one!
