Mechanical Endstop Reinforcers

After having one of my mechanical endstops break, I decided to beef up the limit switch a bit. Using soldered leads to hold a limit switch in place is just asking for failures.

Here are end stop reinforcers for the X, Y, and Z axes on MBI printers.

Should also work with most clones. Tested on an R2x using MBI's "mechanical endstop" and Flash Forge's "axis sensor."
