Stand for Sparkfun small servo

thingiverse

Servo base for Sparkfun's Servo - Generic (Sub-Micro Size) Dimensions of the servo are on its datasheet: Instructions Can be 3D printed or lasercut (I lasercut it in 3mm stock). Based on the datasheet, I modelled the servo in OpenScad, then designed a suitable base around it. See stand.stl Then sliced every 3mm -> dxf , manually repositioned for economy in stand_layout.dxf lasercutting ========= Boltholes are provided to hold everything together with M2 bolts. Cut using the dxf. You'll need at least 6 layers of the small holder cross section plus the base pieces. Any less and the servo won't fit. One of the layers should be the u-shaped one (exit point for servo cable). 4 * M2 bolts thread through the base disk and the holder cross-sections. Nut goes at the top. Check that the bolts won't catch on the servo mechanism. If the bolts are too long, either cut them or add a few more layers. The annular ring simply attaches with e.g. pva glue. It raises the unit above the bolt heads. You may want to screw the servo down to the holder. I found it unnecessary -- the fit is snug. 3DPrinting ======== Not attempted, but should be ok. Modifying ======= The scad file should be self-explanatory. You might want to comment out the $fa and $fs until your final version. Prefix the servo() line in module all()with * to hide it. Last 2 lines determine whether you produce a 3D model or projections: for the 3d model, use: all(); *projections(3); ... and export the result as STL for dxf slices, use: *all(); projections(3); ... and export the result as DXF.
