FuzNuz T-post Insulator

UPDATE 3/9/2020: I tested one of these for a year and it eventually failed at the base of the shaft due to light induced degradation. My recommendation is to print these out of Polycarbonate if you can get it, or otherwise dip your completed insulators in a UV resistant paint. FuzNuz Insulators for T-posts. I am making them in different sizes and lengths, but for now the first one is a 2 inch front of post design. This is a small high strength print so the settings are fairly important. This was done using Glow-In-The-Dark ABS to provide a nice beacon for spotting the electric fence at night. It uses thick walls consisting of three times around the perimeter of the print before doing a light infill of 10% or so. Printed without support at 0.4 mm layer height. It takes 36 minutes to do the front part and 21 minutes to do the back part for a total print time of 57 minutes. Can hold a T-post up by the insulator when attached at the center balanced point and held straight up. Uses about half the plastic as a normal 2 inch T-post insulator (20 grams compared to 11 grams on my scale) and does not require any tools to attach. It attaches by holding the front piece up to the post and sliding the back piece up next to it from behind the post and above the front piece. The rear piece then slides down into the slot securing the two parts together firmly. I've had some trouble with different manufacturers of T-posts. They aren't all the same exactly in design so I'm still working to get a one size fits all solution. Please let me know if you experience any difficulty with installing them or repeated problems of falling off or breaking and I will use that to continue improving the design.
