This is a fully mechanical auto-lock system for sliding gates.

✔️ Fully printable

Designed to lock automatically when the gate slides shut. The internal spring-loaded arm prevents the gate from reopening unless manually lifted.

Tested with gates up to 15 kg.

✅ Print-friendly design

I’d love to see your makes and remixes!
