Here is my attempt at a dice box I made for my son.  This was my first time doing a tool change, and attempting a multi sided carve.  It turned out fairly well considering.  However I left a nasty scratch on the top when I accidentally tried to jog the v-bit without raising it off the work first.

This was using a piece of poplar I got from a big box store.  It is harder to cut than MDF, but I slowed everything down to 600 mm/min at 12000 rpm and had no issues after that.  And on top of that it is really easy to finish this wood, much simpler than trying to paint MDF.

This is using a press fit for the lid, it came in a bit tight but some sandpaper and elbow grease seems to have fixed things up.

I'm struggling to get rid of tool marks from the side of my projects.  Part of the problem is that my 1/8" single flute spiral up cut bit is not capable of doing a plunge cut.  It shutters fairly bad when you plunge and I think that is causing it to flex a lot as well, leaving the marks.

I'm experimenting with ramping in all my cuts, that seems to help, but not around the tabs.  For that I tried using a triangular tab, that helps some but it still leaves a small mark no matter how much filing and sanding I do.  

I ordered a 1/8" dual flute down cut bit to see if that will help at all.  I will report back once it shows up.
