Thanks for the info...

1. If I am able to reduce the diameter by say 1 to 3 inches would that make a significant difference in printing costs? I may be able to go as small as 15" diameter. I would do scaled down version but I want to be able to test it out so it needs to be as close to full scale as possible.

2. Yes, the clips can be incorporated with the rim (I think). Since I'm in the initial design phase, anything is possible at this point.

3. Down the road if I were to produce say 20-30 of them, is there a way to print/produce them as one piece w/ the clips so I dont have to put them together. I.E. injection mold or even a larger scaler 3D printer?

I'm brand new to this. Hair-brained idea has been stewing for some time and I'm finally taking action so lots to learn.

I appreciate the feedback.
