Anyone know how to make a mechanism that replicates this Lego gear?

This thread may also be on vex forum soon, it depends on how fast the mods accept my thingy.

I saw this lego piece that I thought could be useful for a more consistent catapult design. I obviously know I can’t use lego but I looked for a vex alternative. I couldn’t find one so I am now asking the question here.

Here’s what the piece looks like:

The general idea is that if met with enough resistance the inner part of the gear will turn independently from the outer part.

There used to be a vex official slip clutch, but I believe it is now illegal as it’s not on vex.com anymore. as far as I’m aware there is no widely accepted solution to this for vex, but I’m sure there are a wide variety of ways to make a clutch that can be translated to vex if you do enough research.
