Dremel Flex-Shaft Mount for MakerBot
Description
Expect future refinements, but this is the first version that works on my Batch 1 MakerBot.
Instructions
2. Tap a 1/2"-20 thread in the centre hole for the Dremel Flex-Shaft.
3. Print off two MakerBeam-to-M5 Bolt adapter parts (DFB_20100223.stl)
4. Tap the top two Mini-T M3 bolt holes on all printed parts with an M3 or 1/8" thread.
5. Insert the M3 T-bolts from the inside.
6. Loosely bolt M3 nuts on the outside.
7. Clean out Mini-T square holes and press Mini-T parts in.
Note: Even though the Mini-T square holes are 10.1mm in length and width, you may need to tweak skeinforge to print them large enough or be prepared to whittle out the excess.
8. Tighten the Mini-T M3 nuts, screw in the Dremel Flex-Shaft, bolt the assembly on your Z-platform with M5 bolts.
9. Rev your Dremel!

What kind of results have you gotten with this attachment? I am just wondering if this would be a viable solution for etching pcb's.
if it is simular to my developmnents, the quality for etching pcb's will be determined to how stiff your build base is. If the build base can twist, as the copper runs through the cutting blade it will push slightly, therefore making 'curved' straight edges. see http://wiki.makerbot.com/robot... for a few images - to be updated with further results too)
Cloth bot - id love to see how well urs comes out, being a true makerbot(parts may be stiffer as more accuratly cut)

I added your construction to

I really like your makerbeam-mounts.
Skimbal: Skeinforge can create gcode for milling 3d-objects and visolate can generate very efficient gcode for milling PCBs
What a fascinating and useful addition to the Makerbot tool set. What software do you used to drive the mini cnc? Do you have any examples of things you have made using the system?
I am imagining integrating your design into a combined extruder/cnc toolhead. First it would additively build the object with deposited plastic, and then clean up the details with the subtractive Dremel. It would be a great way to solve the problem of accurately sized holes and parts that need to slot together.

Too cool! Love the printed brackets.
