LK4 Bed Leveling Knob

Bed leveling on the LK4 can be frustrating. The back two knobs on the underside of the bed are extremely difficult to get to and close to impossible to turn. For me, at least it seems impossible sometimes. I thought if the knobs were a little bigger it might be easier, and the set-up video on YouTube suggested it. I looked for that maker, but could not find it.
It was tricky getting the hole the right size to slip over the existing knobs. I finally gave up trying to make it with gears and went to a straight round hole to slip on. They fit pretty snug, so don't think you'll need to glue them, but you certainly can if you wish.
