This thing is a simple cap that fits over the cap of a standard water or soda bottle, and holds your small snapshot camera so you can take a picture without having to rest the camera on a stick, railing, etc.
I saw a soda bottle tripod thing here on ThingiVerse, but it was printed in 3 pieces and had to be glued together. Plus it was thick and bulky and had a pivot ball that didn't fit into the socket correctly (it broke the socket when I pushed it in). I designed this camera stand completely from scratch using Autodesk Inventor. I printed it out using the Thing-O-Matic at TechShop and also on a Replicator.
The little post that attaches to the camera's 1/4-20 threaded mount simply pushes in...you don't have to screw it in. I'm not sure how many cycles this will work, but you can always print a new one if it wears out. Also, I would advise that you unscrew the mount from the camera instead of pulling it straight out...there's a chance it could break off if you pull it.
Be careful because the camera might be a little tippy on top of the soda or water bottle. Be careful that the wind doesn't blow the whole thing over and break your camera!
1.) Print it out. I used a Replicator and turned rafting ON, support OFF, 25% fill, and 2 shells. I was surprised that the lack of support did not result in a hairy underside for the top...the replicator drew lines magically across the top as if there was support! You may need support if the top droops for you on your printer.
2.) Push the thing on to the top of a standard water bottle or soda bottle with the cap on. It should fit snuggly. Also, it is best if the bottle is full of liquid.
3.) Push your camera onto the camera mount lug. Just push it straight on...it will slide right in, and there's no need to screw it in.
4.) Take your photo with the self-timer.
5.) To remove the camera, I recommend that you unscrew the camera stand from the camera's 1/4-20 hole instead of pulling it out to avoid breakage of the lug.
