Bash guard designed to fit the rocky mountain altitude (2021+) really well. The intent is that the guard fits the two bosses so tightly forces are instead transferred through that rather than the bolts which would likely break when 3d printed. I have printed a ton of these and they have been PERFECT. smashed them to every rock i could find, they offer a very soft bash experience and stand up to a surprising amount of abuse. But after about 20+ good smashes it is time for a new one. good thing you own a 3d printer right?
