I ordered a few of these to replace worn-out parts on our buggy, but it turns out the little channels on either side of the round part are slightly too narrow. I'm not sure whether the model's dimensions are at fault, or if it's a printer resolution issue.I've been trying to widen them by scraping/cutting away with a craft knife, but it's been surprisingly difficult.Does anyone have any ideas that hopefully don't involve me splashing out too much? I've been considering getting some small files, but I can see them being even more awkward to use...EDIT: sorry about the 'pLA' -- the post submission form was title-casing everything and then apparently submitted it in normal-case... via /r/DIY http://ift.tt/2tZcL4Q
