Cornelius keg portable tap

thingiverse

I didn't like the plastic picnic tap because it had no flow regulation and just looked cheap, nor did I enjoy having the faucet mounted directly on the disconnect as it stressed the O-rings, leaked, and wobbled. So I made myself this fancy device. You just mount it with Velcro tapes and the party begins. What it fits: I think there are two sizes of Cornelius kegs, taller/skinnier ones (which I believe are Pepsi) and shorter/wider ones (which I believe are Coca-Cola). I only have the taller ones, so this fits them (outer diameter between the rubber handles is circa 210mm). If you have the wider keg, please measure the dimensions and post a comment; I'll adapt the design. I made the mount for my European-type faucets. The hole for a shank is 24mm in diameter; I don't know what diameter American-type shanks are. If you need different diameters, leave me a comment; I'll adapt it for your needs. Attention: My first prototype broke in the weak point right under the circular part. The reasons for it breaking were that I used PLA, used layer fan, used unnecessary force (it was a test), and my layer adhesion generally sucks. The design is improved since then: I increased the thickness of the circular part by 30%, increased the outer diameter of the circular part, and extended the parallel reinforcements further up (not yet in the photo) by a few mm. I'm sure the design is now much more robust, but I still recommend doing as much as possible to strengthen that area. My suggestions are: use something stronger than PLA (I used PETG for the second prototype); turn layer fan off for that part; overextrude slightly for that part; increase infill for that part if your slicer allows it; increase nozzle temperature for that part; and remain gentle. I also made a three-part reinforced version. The base is the same, only has extra holes for M4 bolts. The two plates are printed flat, so the layer orientation is much more suitable. I only think you need this if you or your friends get violent when drunk. You can also use some superglue if you want it to become a relic in the future. The thing fits 200mm x 200mm (usable) heatbed. Edit: I removed the non-reinforced version as it was not stiff enough. The reinforced three-piece design should be far enough.
