Screw the set screw in place. You should feel the screw tightening up a lot near the end, but if the hex wrench starts to bend due to stress, go back to step 2 and tap through a bit more and try again.
Stop when the set screw reaches the inside of the housing. Here I show the screw sticking out by 0.5mm or so. Once you reach this depth, unscrew until the set screw is aligned with the wall. If any plastic is bulging out, you can shave it off with an Xacto knife.

- Tighten the set screw by 1/4 turn
- Install the slide
