i created these mods with the help of user Waschbear on the voron discord, there are two versions… the one i use and the one he use's. these may need to be scaled up or down due to printer calibration,settings,etc.. ymmv. the mod has been working well for me! although it has changed my Y input shaper graphs quite a bit. i am currently running an xol toolhead with a moons 17mm motor, the brand of my chain is CNWSL 10x11 i got the chain from Mr. Bezos and it seems like decent quality. you will have to use a 6mm drill bit to enlarge the hole in the last link on the slide through pin version
