Limit switch mount for Sherline CNC (and A2ZCNC base)
thingiverse
This mount is used to hold the limit/home switches on a Sherline CNC mill (which use the Sherline CNC stepper motor mounts). There are two files, one fits the stock Sherline CNC (X,Y & Z) and the other is for the A2Z extended X-Y base upgrade. The file labeled "XY-Slide_mount.stl" is the A2Z version. I designed this to print without any rafts or supports. See instructions tab for assembly tips. Instructions I used Radio Shack Roller Lever Switches (9.5mm spaced mounting holes), but you can pick the same model up from Jameco. (http://www.jameco.com/1/1/536-ss-5gl2-ss-spdt-nc-basic-subminiature-switch-snap.html) To make setup easier, I tapped the holes in the switch with a #4-40 thread and used 3/8" #4-40 screws and washers to hold the switches to this mount. The Sherline motor adapter uses #8-32 bolts, I replaced the two original bolts with 3/4" #8-32 bolts and used a nut to hold the mount in place.
