Banjo String Lifter for Bridge Changes
I designed this last year and have been shipping them with banjo bridge orders and giving them away at events. This string lifter makes it much easier to change a banjo bridge while reducing risk of breakage / issues. These are 3d printed and I made the design publicly available on Thingiverse.

You just slide it under the strings near the bridge, push the lever arm towards the head, and it will relieve the pressure of the strings on the bridge to facilitate changes.
If you want one of these, you can 3d print your own or order a bridge from me and it will come with it.
