Have a 3D printer? I need help, will pay.

[HeroHog]

I need someone with a 3D printer that can make me one of these, a Dremel®-clone rotary tool to 43mm drill press adapter (cheap alternative to Dremel Workstation).  Will gladly pay time, materials and shipping!

I have a resin printer.  You probably want FDM for that, but I'm downloading the files to take a better look.

Dunno, it has to be relatively robust.

I've got an Ender 3v2, I'll get it started.

ETA: looks like a little over 3 hour print. I'm using 4.5 shells and 30% hex infill.

[zxcvbob]

All I have is ABS-like resin.  It's not an engineering resin (they make those) but it's pretty tough.  I'll see if I can print it.  The internal threads will be interesting.  It'll take about an hour and 75¢ worth of resin.  If it prints, I can make another one or two and send 'em to you.  If it fails, well, I'll have fun trying    If I had faith that I could print it, I can make them 2 at a time and maybe 3 in the same amount of time.  But I don't want to waste that much resin until I know it work.

What are the threads supposed to mate?  I have a couple of old Dremels and a recent and smaller Harbor Freight thing and they don't have threads.

I don't even know what that means; are you hollowing it?  Nylon filament or PLA?

Yes it's mostly hollow with 3mm honeycomb.

4.5 shells produces an outer layer about 2mm thick. It alternates between 4 and 5 passes every layer, overlapping them.

I'm using Hatchbox PLA, it's stronger than you think. Plenty strong to hold a dremel.

"They" recommend a lot of fill/bracing but I don't know what filament they are using. I am TOTALLY out of my depth on this stuff and know just enough to be annoying.

I knew PLA was strong, that's why I said FDM might be better suited for this.  I did not know it was stronger than nylon

Speedy say's "Yeah, I knew that" knowingly...

Infill strength is not linear. I've seen where 100% is only marginally stronger than 50% or 30%, but when you get down to 20% strength starts dropping quick. The downside is that 100% takes three times longer than 30%.

[zxcvbob]

With resin printers, the fill density makes no difference in the print time, it only affects how much resin you use (and the strength obviously)  But if you try to print something too large it can fail if you don't hollow it just from having too much surface area to release properly from the screen. (technically the FEP, not the screen) 

I've not hollowed anything yet, the slicer I'm using sucks at hollowing unless you pay for the "pro" version.  I wouldn't be totally opposed to that, except it's a subscription service rather than a one-time license fee   

I haven't tried printing it yet, I got distracted trying to make a squirrel baffle for one of the bird feeders.

I trust ya, bud! THANKS.

One is done. First pass on the base layer didn't stick as well as it should have, and the first thread looks like crap. It threads onto my Dremel and holds solid, but I changed a few settings and am running another.

[zxcvbob]

I'm fixin' to try one.    The first thread has me a little worried too, it should be easy after that.

ETA: I found one of my old Dremels and it does have threads; looks like about 18mm.  I never noticed that before because there's a collar screwed down over it that doesn't do anything except hide and protect the threads.

[zxcvbob]

Just finished and it looks pretty good.  It fits my ancient Dremel.  PM me your address and whether you want one or two or "no thanks"   (I'm fine with any of those.)  Looks like Bedlamite is making you one too and his is made with stronger plastic.  Mine is likely more precise but not by much, just by the nature of the process.  It was fun seeing if I could print those inside threads.

[bedlamite]

I've got two of them that should work. I'm still not happy about how the first layer looks, It might be because the wall thickness is double what I normally use. Either way, same as zxcbob, send me a PM with an address and they will be on the way.

I ain't afeared! If ya can't find me in less than 3 or 4 steps on the web, ya ain't tryin'! 

THANKS GUYS!
Send one if ya have a press to use one in or have another friend that can use one. One for a backup is cool but not a requirement. PM me how much and where/how to get it to ya.

I'm using it to drill Pearls for PinkPigPart's jewelry that she makes.

I've got one packaged up for ya, I'll try to get it in the mail on Monday.  (if not, I'll take it to east Texas with me next week and mail it from there and you might get it faster, LOL)  You don't owe me anything unless the postage costs a fortune.  Get one from bedlamite too; use whichever works better for you and you'll have another for a spare.

[HeroHog]

THANKS AGAIN, GUYS!

[HeroHog]

Dunno who Beebe is but, THANKS! Works PERFECTLY!



The silver thing on the standard Dremel vice is a Pearl vice for drilling pearls.

[zxcvbob]

The one I sent was gray, so that's not it :D  It should have got there today but I haven't checked the tracking.

[HeroHog]

@bedlamite, THanks! They are perfect!

@zxcvbob, Looking forward to it, THANKS!

[bedlamite]

Glad to hear it works.

Someone's got to do something about these ghost adapters.
