I can't believe how quickly people become sheep. On social media, the guys that love 3D printed inserts will happily pay for those overpriced, low-quality 3D prints and then regurgitate that information all over. They will sign off their post with FUPA 3D Inserts or whatever terribly named brand they want to fanboi for. It's so pathetic that I just have to laugh at those guys!
You best believe they pay more for the 3d printed inserts than they pay for the actual rubber that already comes with foam inserts.
