About this 3D model

I tried out a connector piece from another design and didn't like the result so I went ahead and designed my own. I'm using it to connect the vertical extrusions to the horizontal extrusions for an AM8 conversion. The size is adequate and there seems to be just enough room for movement in the hole to get it into the correct orientation. There are no ridges to guide it along the slots so this part relies more on friction and a tight fit than machined parts. Designed to be printed as uploaded, not as pictured.
