3030 extrusion end cap

thingiverse

This is a basic end cap designed specifically for use with the 15-series 3" x 3" T-slotted aluminum profiles of the 3030 series. The idea behind it was to create a simple ABS cap that could be purchased from 8020.net for under $2, but I wanted to take it to the next level by incorporating mounting screws that sit flush in counterbores.
