Holes for the 3 screws need to be drilled after printing the part. For #6 screws, drill the holes using a #25 (0.1495") drill.
Additional Parts Needed
The limit switch we have tested and recommend is shown in the picture above. This switch allows for connecting it as either normally-open or normally-closed. It is from McMaster-Carr, part number 7779K13.
3 sets of fasteners are needed.
- 2 screws, washers, & nuts for attaching the limit switch to the mount. Recommend these be #6-32.
- 1 screw, washer, & a wing nut is needed to tighten the mount's connection to the arm. Recommend this be #6-32 carriage screw.
