Dremel Flex-Shaft + MakerBot + MakerBeam + OpenSCAD = (Micro CNC Mill | Drill Press)Expect future refinements, but this is the first version that works on my Batch 1 MakerBot.Print off a Dremel Flex-Shaft Mount (DFM_20100223.stl)Tap a 1/2"-20 thread in the centre hole for the Dremel Flex-Shaft.Print off two MakerBeam-to-M5 Bolt adapter parts (DFB_20100223.stl)Tap the top two Mini-T M3 bolt holes on all printed parts with an M3 or 1/8" thread.Insert the M3 T-bolts from the inside.Loosely bolt M3 nuts on the outside.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.Tighten the Mini-T M3 nuts, screw in the Dremel Flex-Shaft, bolt the assembly on your Z-platform with M5 bolts.
