I want to enhance my skills in 123D Design so I can create something new every day. Today, it's finally done! To assemble the design, print two top-bottom.stl files, which are approximately 102mm high, and a number of your choice extension.stl file, which is about 60mm tall. The design already has a 3mm hole, but after printing, the diameter becomes roughly 2.5mm. To secure it together, use something that fits into the holes. I used 15mm pieces of 2.5mm welding wire, and glued them all in place. That's it! To prevent outdoor damage, attach a thin fishing line with two small hooks (see photo 4) to keep it stable.
