Standard Barrel/Drum Bung/Plug/Adapter for S64-5 Buttress Threads (SCAD)

THERE ARE NO ACTUAL FILES HERE OTHER THAN THE PREVIEW. I CAN'T UPLOAD THEM. IF YOU WANT TO DOWNLOAD THE MODELS, YOU HAVE TO GO HERE INSTEAD: https://www.printables.com/model/1652824-standard-barreldrum-bungplugadapter-for-s64-5-butt I cannot upload the archive or any large files without them either failing or ending up corrupted. All file transfers randomly terminate after about 90-120 seconds, so if I can't move that much at 300kbps, then I can't upload it here. Thingiverse has always been garbage, but with the recent changes, it is no longer usable. //////////////////////////////////////////////////////////////////////////////////////////// This is a bung/plug/adapter for plastic barrels/drums with the ubiquitous M64/S64 buttress threads. (64mm major diameter, 5mm pitch, 45 degree included angle). Unlike all the other printable designs I found, this one actually includes the necessary flange and gasket, and uses the normal cruciform wrench instead of some reinvented socket style. The result is a plug which should be better at sealing, and it should be more resistant to getting stuck and mangled. That's why those features exist. It also isn't full of mesh defects. If the wrench socket is undesired, it can be omitted. If you want a threaded port for a tap or pipe fitting, it can be added. Various NPT sizes are supported. There is also functionality to add a second port (e.g. for an inlet hose or outlet siphon plus a vent port). Double ports can be sized independently, and are automatically spaced apart as far as is allowed by minimum wall thickness. If you want garden hose threads, install a thread adapter. Unless you like juggling an entire roll of hose, a female GHT connection should be capable of swiveling freely. Use a GHT-NPT adapter -- a real one that won't just snap off. The TPU gasket is going to be stiffer than the typical soft flat gasket or ring. The as-printed surface of the bung flange may be rough enough that you might consider using silicone or other adhesive between the gasket and flange. The gasket is smaller than the threads, but can be walked down around the threads until it tucks into its groove beneath the threads. I'm using SUNLU 90A TPU, and printing with 3 top/bottom layers and 15-20% infill seems okay. I printed the initial test parts in PLA, 2 shells, 20% infill, with supports only on the underside of the flange. That said, 3-4 shells may make more sense for parts with ports, or if you want to risk allowing the plug to actively hold back liquid. Prerendered STL files are included for blind and threaded parts, both with and without wrench sockets. An example assortment of double-port non-socketed bungs are also included. The gasket STL is in the directory with the blind plugs. I'd like this file to support S56 and S70 sizes as well, but I don't have examples, and I can find no drawings or description of the form.
