I found out that though my JST tweezers, being very effective for pulling out and connecting back JST connectors, it's difficult to use it in tight spaces. Learned it the hard way when I had my first broken filament in the Bambu Lab AMS.
Just by having the tweezers slightly bent makes a huge difference to be able to reach the JST connectors so I created another version that is angled by 60°.
Personally, I find the angled version more ergonomic but equally as effective as the original design.
