This is a replacement for the leg end caps that support the glass table top of a patio type table. This cap is placed onto the extruded leg end that contacts the metal edging of most glass topped tables commonly used for outdoors. The original caps were made of a clear looking nylon. Over time they deteriorated. I found TPU, flexible filament works the best. I made them using Amazon's tpu filament. Printing these I used a 3D printer that has a direct drive hotend that allows easy printing of tpu type filament. It is a stock Dovov S2 Printer.
