Not sure why that didn't work... https://i.imgur.com/SkoYjmQ.png https://i.imgur.com/0kyfiF1.png
One of the rods popped out of its slot in the sliding block (first picture). I put it back in, but it isn't fitting snugly like the other blocks are, and it looks like it will eventually work its way back out (second picture). What is a long term solution to this? Should I order another sliding block?
