25mm Product Display Turntable Top

I wanted a small flat black turntable top for my solar powered display turner thingy, so I printed one out of black carbon fiber PLA. The turntable has a square drive shaft measuring about 3.8mm, so I made the square hole 4mm. It's 25mm in diameter which I'll use for smaller items. I'm probably going to be using this to make videos of some of my 3D prints.
