Plug for miniVICE X2

I have been using the excellent paint handle / mini vice from Chito (https://makerworld.com/en/models/1187363-minivice-x2-series-modular-mini-painting-handle#profileId-1198569). He has a variant with adapters on the bottom so it is either ergonomic or fits into dropper / citadel slots. I have been using lead shot in these adapters to add further weight but switching adapters is risky as the shot can spill. This is a plug to screw in and “lock” in the shot to make swapping out adapters easier. The fit depends on the quality of the threads on your handle print, sometimes it is worth reducing the plug dimension to 0.98 if you are having issues with the threads.
