A1 Hub Cap Lock

This is version 2 fits better and just does a better job at holding the top of the hub on.If you have had the cap to the hub pop off this will help keep it in place. I also recommend using one of the many PTFE Cable Guides in addition to this.This cap lock is designed to allow the filament jam detection system to still work properly.
