Well I bought some ABS because it wasnt as long as the pvc so it could fit in my car, and it was cheaper where I was getting my materials. Im covering my snap in orange and green tape when im done, so I dont think that will be a problem. And lastly the washer that was suggested, it fits in quite nicely with a bit of lube.
That is utterly one of the most spectacular things I have ever seen!
My one question is how much trouble does it have for the clip falling out? (or did i miss something?)
EDIT:I just read more carefully, sorry.
