I needed this hole pattern for a dual-extruder mount: http://www.thingiverse.com/thing:6632 I couldn't just extrude the original .DXF in OpenSCAD, so I sat down and took precise measurements and created my own replica instead.Completely parametric, if you need to adjust any of the dimensions yourself, but this does include a perfect set of dimensions and boltholes, which I'll be applying to the MK5 Wade's-style tensioner shortly.Marked WIP because it's the official home of the Dual-Extruder mount .SCAD.Do whatever you want. I don't think this'll be useful for many people directly, just the bolt/hole pattern.UPDATE:Ok, the word is out. Ever since I published this, it secretly also contained the plans for this: http://www.thingiverse.com/thing:6632And still does, if you need them.UPDATE: .scad file updated for dual mount version. boltholes unchanged.
