Technic D20 I slapped together one afternoon

It's about 4 inches tall and is comprised of 4 different types of bricks. I just tried to make a list of the parts but technic stuff is so hard to succinctly describe sometimes. Three way axle connectors? God (the bricklink database) only knows what Lego calls them. Thankfully it isn't hard to figure out what those 4 parts are. The only one that isn't evident is the angled connector in black is a #4. Any other angle won't work, at least not for a D20.

Since there's an axle hole on each face, you could theoretically add more proper die faces with numbers or whatever you like.
