This grip attaches directly to the lever inside the pump grip, so it doesn't get jammed up as easily. It's also a bit bigger so you can fit more than two fingers on the grip.
Hardware required is 4x m3 nuts and 4x m3x25 socket head machine screws. The holes for the nuts are designed to be tight, and they will likely require using the screws to pull them in and seat them before assembly. Step and Fusion360 files are included if you want to mess with the design or the tolerances, plz don't bully me about my workflow…
