I've been having troubles getting the oem pegs to stay in place. I finally made my own when one fell out on a ride & I couldn't find it again.

If printed right, it should slide in without much force but should take some strength to take back out. It shouldn't slowly rattle out on it's own. If it doesn't fit properly, try scaling the model up or down slightly. This model requires pretty precise sizing, so it may not come out sized right on the first print. I'd recommend printing your first one in the standard profile, then print the final one in 0.08 once you have it coming out right for minimal layer lines. I've also released the source here: https://drive.google.com/drive/folders/1diCmAIX-KfPC9UOpCqBX7ajm4-Fpo7vr?usp=sharing. I've made it very easy to precisely tweak the key measurements in freecad with no previous experience using the program. I've left instructions in the zip file along with my email. Feel free to contact me if you'd like some help.
