REGALO BABY GATE EXTRA LOCK

thingiverse

You'll need an Ender 3 roller wheel. Remove the bearings and spacer from the original part, then place them into the new part. Next, you'll require an M5 bolt of suitable length; I suggest purchasing an M5 thread rivet for bolting onto the gate. To secure it, drill a hole in the center and follow the rivet's instructions. Note that after installing this solution, my son discovered how to open it within two weeks, so I'm working on a more effective fix when time permits.
