Purpose / Problem
Protect your LR3's Y limit switches.
The LR3 Y axis limit switches are proud and prone to being knocked when LR3 is being stored/relocated. Spring metal arms on the switches often fly out and are a PITA to find and reattach.
This guard is designed to protect the limit switch, while also being very easy to mount to the existing Y drive mount.
Created for my LR3 build after spring arms came off 3+ times.
Consider printing in PETG. Typically, PLA is brittle and less flexible.
Layer line orientation isn't optimal wrt strength, but design seems good enough to me. Will mod if it fails next time the corner gets bashed when moving my LR3 between sled/table/dev-station. Maybe the suboptimal layer orientation makes this a good sacrificial part that'll crumple and absorb kinetic energy rather than the main parts, no idea if this makes sense or is a baseless armchair engineering opinion. Thoughts/feedback appreciated…
Alternatives
See https://forum.v1e.com/t/limit-switch-arms/36804, some folks are happily using more robust hall effect switches (magnetic based).
