One of the things that I keep telling myself that I need to learn how to do is 3D printing. This morning, I ran across a couple more 3D printing projects for ham radio that I thought I\u2019d pass along.<\/span><\/span><\/p>\n These parts are made for use with 1-in. PVC pipe and 1-in. Harbor Freight tape measure steel. You can use electrical tape to attach the element holders to the side of the pipe, and use the driven element bridge to give structural rigidity across the driven dipole element. I have used this with up to 5 elements on 2m with good success. When not using the antenna, just pinch the elements to remove them from the holders, and store them INSIDE the tube! you can add some end caps to make this ultra portable. Use these parts with any of the multitude of tape measure YAGI design guides online.<\/span><\/span><\/p>\n Here\u2019s a look at an antenna made with these parts:<\/span><\/span><\/p>\n The element holders are attached to the boom with electrical tape in the photo above. While I haven\u2019t tried it, I\u2019d suggest that the antenna might be a bit more robust if you could screw or perhaps glue the holders to the boom.<\/span><\/span><\/p>\n There are lots of other cool amateur radio 3D printing projects available on Thingiverse (https:\/\/www.thingiverse.com\/search?q=ham+radio&dwh=415b6d8da129c3c). Browsing through the list quickly, here are just two that look like they might be useful to me:<\/span><\/span><\/p>\n![\"tape-measure-yagi-element-holder\"](\"https:\/\/k6bj.org\/wordpress\/wp-content\/uploads\/2016\/06\/tape-measure-yagi-element-holder.jpg\")
