I'm designing a cradle to hold a GoPro camera to the bottom of an AR Drone. It's obviously not complete, but I wanted to make sure I had designed the clearances for the male and female sections that join the two halves correctly. This doing 3d modeling. Right now I have a .5mm clearance on each side, but that leaves the parts with a 1mm wall which is close to the minium. Should I make the walls thicker? I would like the parts to fit together as snugly as possible, can I reduce the clearance any? My plan is to use strong and flexible plastic, polished.
My overall goal it to make it light. Strength is not as much of a factor, but I don't want it to fall apart under it's own weight. It just doesn't have to survive a 50' drop.

For separately printed parts, you might actually consider "negative clearance" - make the parts slightly overlap. Then, when you receive the peice, do some sanding to optimize the fit. This would ensure that it's not too loose.

Thanks for the suggestion. Any thoughts on the durability? The part that's going to doing most of the flexing is only 1mm thick. I'm hoping it's thin enough to be flexible but isnt going to break too easily.
