Another round of keychains

This is actually the first non-“one off” project I’ve done on my Shapeoko, I’d precut the blanks using traditional woodworking tools so I wasn’t cutting these from a larger piece, which meant I had lots of times to cleanup my small workspace and draw up plans for other stuff while I swapped the piece out every few minutes but they all came out fine. I had a lot of ‘fuzzies’ to clean up but didn’t get too obsessive about it. I am however realizing if I’m going to do these types of simple engravings I should really get some downcut bits instead of the c3d upcut 1/32 mills to help minimize that. Has anyone with experience found that feeds & speeds usually differ between downcut and upcut versions of otherwise similarly sized bits?
