5/16 rounded cap

I needed a rod cap for my cr-10s frame brace mod found here: https://www.thingiverse.com/thing:2491003 as the rods I bought were longer, but it allow me to move the installation to the front of the CR-10s. Next I took: https://www.thingiverse.com/thing:1273153 then added a rounded top to prevent accidental injuries.
