Hey there, thanks for checking out my model. I'm still trying to get better at CAD, but recently I needed a grip for a hand brake, and I thought I would make one instead of just downloading one, so I made this guy a hexgrip handle for hand brakes. All you need is a 30mm M8 threaded rod. I made my own with a thredding die, but you can just get one online for 2-4$
