Summary

These are cupcake endstop mounts for the Gen 4 electronics endstops. (http://store.makerbot.com/mechanical-endstop-v1-2.html) I wanted endstop mounts that did not require me to drill holes in my cupcake. These are the -x and -y mounts for the original x and y axis. (not lowrider)

Instructions

Using 4 3mm x 25mm Screws you can remove the top two bolts on the X front retaining bracket and insert the 25mm screws in their place. the X axis mounts onto these screws with the previous nuts. Then remove the front left bearing holding screws and replace with the 25mm screws with the Y axis mount on the bottom surface of the bot. Attach the endstops to the two holes in the top of each mount using 2 3mm x 10mm screws per mount, these do not require nuts as the holes are undersized to allow them to bite into the mount. I mounted the z endstop using a hole for the extruder board and an existing random hole in the side of the bot.
