Dremel mill XY table

This is an XY table for a desktop dremel-powered vertical mill. The rest of the assembly isn't completed yet, but I after seeing NickAmes' work ( http://www.thingiverse.com/thing:2956 ), I figured I should post this and see if it might be useful to his project. I still plan on finishing this when I get a chance, but collaboration can't hurt.

The basic idea here is that the X and Y stages are the same part and can be assembled into as long a stage as you like. X and Y stages are held together by a pair of M3 all-thread rods which are tightened by nuts on each end to place the stage in compression. each slide has a captured M6 nut which engages an M6 all-thread rod with a handle something like this:

The slides are keyed together with 3mm keys (not yet modeled) and fastened by 4-8 M3 SHCS. The whole affair is attached to the table or bench by screws through the Y-axis endcaps. T-nuts (not yet modeled) would have a captive nut so that parts can be secured to the x-stage. As-is it might suffice as an XY table for an existing drill press, if you have one.
