    Hi. I have an Ender3 but have upgraded to a Duet3d Wifi board. Wonderful web interface, and all changes are via Goode. Very impressed with it.

    For wireless... Replace the microsd with one of the micro to regular sd adapters (little 6$ ribbon cord)

    Then use one of the wifi sdcards. Do a quick search most are hackable. You write one byte to the card to turn it on, then it's a NAS drive in essence. Walk to printer select file and go. No need to touch it.

    Translation: You can connect you 3D printer to you home WiFi network, it's very handy but not, at all, necessary if you just want to print stuff.

    Well... some how we got in our heads that we needed a 12mm adapter, it turns out the plug holes are 14mm and we were already setup (old age will do that to you):mad: At lest my version of the adapter only cost about 10 cents to make.

    I did pressure test it anyway (as high as I could by just putting my thumb over the hole, about 80psi which is what I set the regulator for). I was surprised how well the hose coupling worked, nice and tight, nothing leaked. I'll print a new one to see how well the threads work.

    Oh well, screwing around with stuff is half the fun.

    The metal one (made by a fellow hangar bum) is on the left.

    I'd never fit in with your EAA group. I'm way too alternate engineering to fit in. ;):(

    The last time I needed one of these I just beat the ceramic out of an old plug and brazed in a 1/4" pipe. I's crooked, ugly, doesn't leak and still somewhere in the bottom of the "I might need this again" tool drawer.

    the compression testers come with those fittings however they do get lost., and the small NGK plugs .....would be another purchase and shipping charge. Had a retired friend of mine once showed me the hinge he made for his shed.

    You just described the 3 or 4 that are laying around my garage somewhere. The problem was we thought we needed a smaller one that nobody had, or even the right plug to make one out of.

    I once made a large 3D printed cap to to simulate an IP test. It was sealed with o-rings at its interface. What I found was that the 3D print was so porous that it leaked like a sieve. You might want to coat that adapter in CA or thin epoxy or perhaps brush on experimental airplane gas tank sealer. But then again, 3D printing has come a long way so maybe yours is not as porous.

    Let me know how it goes.

    I was concerned about that but my very unscientific -thumb over the hole at 80 psi- test didn't show a problem. If it did I was just going to coat the inside with something like Elmer's glue and pressurize it to force gunk in to the pores.

    There are so many print settings though. At least I know my current settings seem to make a pretty airtight material.

    That is the curse of needing a tool NOW. You end up making one. :rolleyes:

    We've 3d printed vacuum boxes for doing small composite repsirs at work. At least using the makerbot, we had to print full infill and cost the box in epoxy to prevent leaks.

    Water and airtight aren't exactly "easy" to achieve. You certainly won't get there with stock profiles.

    It could have been leaking, it just wasn't leaking enough for me to tell in a quick and dirty "this otta work" test.

    If I was *deliberately trying to make an airtight part I'd turn the parts fan way down, increase the extruder temp and slow the print speed down. But just using the generic PETG settings seems to have worked pretty well.

    Water/airtight I've got a profile tweaked from a TPU profile - no retraction, inside out, slight overextrusion, minimal cooling. And yeah super hot...

    Got to see the new Ender 5 Plus in person this morning.

    If you're currently shopping... Definitely worth a look. 350x350x400mm build area. So 2" bigger than the cr10s.

    There will be some neat options with this setup to come I'm sure.
