NEMA-11 stepper driven linear stage

thingiverse

This is a work in progress, but already working. I attach the parametric designs (currently compiled for a NEMA11) that permit to couple a stepper motor with a linear stage (in my case, a Newport M-UMR8.25).http://www.phidgets.com/products.php?category=23&product_id=3300_0http://search.newport.com/?x2=sku&q2=M-UMR8.25 I provide two versions of the shaft coupler: Shaft.stl: direct coupling, need fine polishing touches and alignment Shaft2 - a, b and c: articulated coupler (preferred options) Instructions MakerBot Replicator 2x Printed with raft and purge walls in ABS and dissolvable filament. Infill 15%, Shells 4, Layer 0.2mm Used aprons, visible in 3D rendering as well. -- bracket -- Front plate and bottom plate: bore holes -- shaft coupler -- Front: bore hole Sides: tapped holes for M3 -- articulated shaft -- All bore holes were designed for M3 screws, but on my printer and with the printer options set, requires a bit of finishing touches or M2.5.
