Printed DNA30 Bottom Feeder

Those are some pretty cool 510s, but the problem with 'em is the diameter of their tops and the air-slots. What this means is there's no way to get a small atty like a Cyclone to seal against the the top of the 510 or the top of the mod with an o-ring. I wonder if Dennis could be convinced to make some of the 510 tops with an o-ring groove instead of those four slots?
Sorry to barge in unexpected, but this is just curious. In rossum's pic, couldn't this blue groove actually be achieved by drilling all of the material inside the blue ring down deep enough for an oring? One would lose a bit of the threading, but then the connector would work both with and without the oring, and the connector would be universal for either bottom feeders or non bottom feeders. The process of drilling seems easier than cutting a groove. Any thoughts on this?
Also there seems to be a discrepancy in Dennis's description. It sounds like it takes a 18g needle, but the ID is 2mm? What did I miss here?

FWIW... a drip tip O-ring makes for a perfect seal with no FD modding needed

Hey Asdaq! You can always drop in here.
With the new FD510, there are a number of way to address this with a bit of modding. (see - a perfect mod by TyCreek!).
I sent Dennis a note earlier asking him if were possible to get a flat top version. That would be the easiest solution here. But I really want to see how his set-up seals between the SS hypo tube and brass connector. Also with out a screw/nut setup, I dont know how you can set a height adjustment or if its just one size fits all. It would have also been nice if he put a barb or screw threading on the end of the connector to beef up the compression seal on the bottle tip.

Hiya gdeal, I've kept my eye on this thread.
Tycreek looks like he has the simplest solution, I didn't know the FD connector already has a recess for an o-ring to fit in. Much better than hogging out more material. If it were a flat top FD without the 4 grooves there would still be a chance for juice to seep through the strictly metal on metal connection, as given any sort of chance juice loves to creep.

OK, I'm obviously blind in one eye and can't see out the other, 'cause I didn't notice that an o-ring would fit in that space.FWIW... a drip tip O-ring makes for a perfect seal with no FD modding needed

Interestingly enough, the older 510 "insert" that's in the existing design also has a space where a drip-tip o-ring might fit.
Very nice....shiny too. So the thickness of the top is now 1mm?
I think I missed something with the newest 3.1 George, that magnet looks very thin, much thinner then the original ones, I have the new internals being built as we speak, what is the new magnet?
lol....Thanks and you can thank Youtube...I had Alt-J playing in the background and you tube flagged me. So they force you to put some no-name lame music in the track or its just a silent video. I could have redone the video and droned on with out music on what I was doing, but I didnt want to insult any body cause its a really straight forward simple build. So it was a choice between generic weather channel, hip-hop, death metal etc... I went with weather channel.
I like the Drip Tip O-Ring for sealing BF. Less juice wander and pretty easy to make a ridge for it to seal on if there isn't one already on the 510 base. Best thing is that the ring stays on the atty and takes most of the juice with it when removed for a flush. Not falling off under running water and going down the drain is priceless!
The new magnets are 3/16th. The old magnets are 1/4". I posted on this earlier. Shapeways went to new system. Every time the 1/4" magnet design was being made for someone, they sent out this obnoxious disclaimer email about a thin wall (between the magnet and the mini-connector) and that its below their guarantee threshold. I sent them numerous emails that the threshold was not meaningful for the integrity of the design and that they should put a note in the file and just print the part. It printed just fine for everyone, it just didnt maintain its rounded shape for the magnet. In the real world, after you inserted the magnet, that "thin wall" was just fine. I think 4nic8's part was the first one printed after they went to new system. Anyway, they wouldnt play nice, so I changed the magnet to the small diamter and no more emails from Shapeways...just printed parts.
The small diameter magnet is only slightly less powerful. The only difference is how much pull you initially need to do to get the top cap off. With the 1/4 it was a tug... With the 3/16th it feels a little more natural with the resistance.
