Featured Thing!

Description

This is a makerbot-printable dremel based milling machine, and my entry for the make/makerbot contest. I wasn't able to finish printing it before the deadline, so it is untested, and should be regarded as a prototype. After I finish printing, I will release a revised version that will fix any bugs that come up.

The axises move on dovetail slides. When completed, it will have a travel of 11cm on the x axis, 5cm on the y axis, and 10cm on the z axis.

So far, I have printed half of the x axis and part of the y axis. The dovetail slide moves freely with little slack or wobble, even though the print warped. This makes the rest of the machine look very feasible, and I'm confident that it will be able to machine aluminum (shallow cuts, of course) when it's finished.

If you've ever looked at the way dremel hooks up their stuff, it's actually a very simple screw on ring at the tip. Bolts the dremel in quite securely.
Could you post the STLs separately so they get rendered and shown on this page? Would be great!
Ok, I see what you had in mind. Seems to me it should work ok - there are several ways to do it. It might be a good idea to thread the dremel into the mount, as in the link above.

I have uploaded shat I have for the version I was putting together - basically just an XY table at this point:

Take a look and let me know what you think.

Instructions

This is a prototype, and has not been fully tested. Although it should work in principle, it is considerably less polished than a finished piece should be, and there are bound to be problems. I don't recommend that you build it just yet. After it has been printed and the bugs have been ironed out, I will release a finished version.

Holy moly, I was just working on a dremel mill! Nice work! How are the parts of the X-axis attached to each other? It looks like a they're bolted end to end. I was looking into a hollow structure with M3 all-thread running through to hold the parts together in tension. I'll post what I have and erhaps we can collaborate.

Also, do you suppose you could post a screenshot of the dremel mount? I'm working on a modified version of the one here:

so I'd very much like to see your concept.
I haven't given much thought to the dremel mount yet, but I was thinking I would use a simple contoured clamp. After seeing the link you posted I think this probably won't be enough.

The x-axis parts are bolted and glued together.

Wow, awesome! With the dremel lathe that's already here we are well on our way to a printable mini-machine shop (powered by dremels!). A lot of work went into this, and I'm sure a lot more will go into it still, so I just want to say thanks, and great job! 8-)
Cool.
Habe you considered combining your Z-axis with my existing XY-Table?
