Swing/Flip Top Easy Cap Grolsch Styled Converter for Longneck and Bomber Bottles

thingiverse

After growing tired of browsing homebrew websites looking for swing top bottles on the cheap and finding out that shipping is way too much, and that all nearby homebrew supply stores are at least 2 hours from here, I decided to come up with a way to rig up my own flip top bottles.This is the result from that. I also borrowed the hinge design from rohingosling's Parametric hinge. Breaking the hinge loose is optional, and I really don't recommend it, unless you're having difficulty getting this around the bell and crown of your bottle. As for me, I managed to get this on a 12 oz amber bottle, and a 22 oz bomber bottle that I found at a flea market. I've already gotten a few likes and a few people have added it to their collections, so I'm going to see if I can find a way to make it work with other types of bottles, like soda and root beer not just limited to glass beer bottles. If there's a bottle you would like this to work with, feel free to let me know and if I can find them anywhere, I'll grab one when time frees up, and try to make it to fit one of those. I just tried it on a twist off Yuengling bottle as of the time I'm writing this update and it works well with them, too, but it won't fit a Shiner Bock yet. 7/28/18: Came up with a new design. Thought it would be cool to have some kind of nicer looking design, something to be less bland, I guess. I figured it would be cool to have a barrel shaped piece on it, but it looks more like a chinese lantern now, so I deem part 2 the chinese lantern, barrelv3_1. This is kind of entertaining, and may come up with something else, too. I'm not sure yet. Also decide to make an attempt at an "economy" version, first version of it failed because there wasn't enough hinges on and it broke after being opened and closed repeatedly. This one uses a lot less filament, 4g at 33 percent infill and .3 resolution, while serving the same purpose. still works great on my 12 oz bottles, haven't tried it on others yet. The economy one has been flipped to print upside down to save on filament, and the rest print right side up. Be sure to take note of which side is the top, I accidentally put my "Lantern" one on upside down and it took me a few minutes to realize it. 7/29/18, I played around with a cordless drill, poked my finger a few times, but found what I believe to be the right measurement to fit it on twist off bottles that don't have the bell underneath the crown. bottom hole works well for those. Will update with photos when I find out how those work.
