This is a remix of Oliver84's remix of 3D-IN's Modular Jar. All the credit goes to 3D-IN which made the original design I remixed this from. They had a great design but putting the end pieces required glue so I remixed this so that all of the pieces can be screwed on and off, including the end pieces. This works much better for my purpose.

I created some new pieces with Male and Female Threads for a truly modular design, they are also scale-able if you need larger containers.

Note: I printed these with supports on areas that touch the build surface. This helps keep the threads in tact.
