Hey guys, I have been trying to think of some simple things that may be expensive or inexpensive to 3D print that would be useful. I saw on here someone 3D printed an SD card holder which I thought was a good idea. I have 3D printed Carabiner clips and am in the process of camera arm bases so they can be left in the tree, and a tripod adapter for a camera arm. I was just wondering if there are any ideas out there that could be used to save money? I am not asking for proprietary info of new inventions! lol Thanks!
