I want a stand just for tips! I have a stand that's working for my mods and my tanks - I just accidentally seem to have developed a little collection of tips... And I'd kind of like them all lined up standing...I keep knocking 'em all over when I try to grab one... Anyone have a stand just for their drip tips? please post a pic or link. And if you MADE one or happen to know - what size hole would I drill to hold a 510 tip?
