SMA10 Double LM10UU Lock Holder

My LM10UU bearing cases hold two LM10UU instead of one, just like a double LM10UU bearing. Since I had to remove the safety locks on the standard SMA10 case, to fit two bearing instead of one, the bearings tend to come out of the case after long/fast prints. This thing locks the bearing case and the bearings are locked inside.
