I only found this recently after messing around with a bunch of other failed pegs and peg systems. I've seen pegs for wood, metal, plastic, even skadis boards, so you find or make your peg and then attach any of the models. Then in the future, if you switch boards, you can move your models to your new board without reprinting them.
My biggest complaints of most pegboard models and how Sy's peglock solves them
This system fixes these issues by printing the peg separately in an orientation that puts the most strength through the highest stress area and separating the models from the peg for much wider adoption.
I've included some hooks I've found in this collection but I've only printed/tested the Husky myself. I think this is the origin model on printables but I've seen it in other sites as well. For more pegs and models, search peglock
