Did some material comparisons

I wanted to print some items that were simple, with corners, a rod, ring and needed some tight tolerances....so printed that symbol thing from harry potter. Razz

Dimensions in inches
Square shaft in middle is .1. The rod is about .043. rod to circle clearance is about .005. Clearance from circle to top column is .005, same for bottom of circle. Triangle width is .1. radius around each corner about .09. top hole diameter .03. Thickness is .0625. if you would like a dimension that I did not list just let me know.

White detail came out nice, flexible, rounded corners. Fuzzy. Not good for higher tolerance object. The circle in the middle did not move at all, so I forced the spin and it broke. As you can see when printed the rod circle and adjacent melded together.

Transparent detail. Better than the White detail as in edges, kinda the same with the melding together.

The best one was the Frosted Ultra Detail. Came out great. Spins with no problem, strong with flex and nice clean cut edges. Would still need to be cleaned up from some of the fuzz.

These came in a previous order and did not make the video, but I did take pictures.
Also did one in black strong and flexible was the same as the Frosted Ultra Detail, just more of a hard rubber feel, like a slice of tire
I Also did one in the black detail that is the same as the white detail

Did another tank also is white strong and flexible polished. Bottom was a little wavy, but fine for what it is. I did have the cylinder hollowed out but for some reason it was not when I received. I took a paper clip to it and material in powder form came out like a was pouring out a pixy stick. 

Video of items above. And yes my nose was whistling (0 0). Dont need sound to watch
