Actobotics C-Channel End Cover - No Nut Required

thingiverse

I recently came across a similar setup that involved a square nut, but I decided to go with a different approach. Instead of using 6-32 threaded screws, I opted for 1/4" hardware. Thankfully, no additional parts were required as the screws will self-thread into place. The two L-shaped mounting portions held up relatively well under tension, proving to be quite secure.
