Yet Another Child Lock

thingiverse

I've tried out multiple child locks, but none have worked effectively. One lock that did work is the magnetic one, though we had an issue with unlocking it. This latch requires a hole to be drilled into the top counter, but nothing is visible from above. The latch has a sliding length of 10mm and uses a spring to make it slightly harder for kids to open it up. You can attach it using double-sided adhesive tape.
