You need:

1. One 3D-printed Childproof cable protector
2. One badge reel (11mm thick 32mm dia) - remove metal clip
3. One cable tie (zip tie)
4. [optional] One small (15mm dia) keyring or cable clip - to prevent slim cable from pulled out.

Installation:

1. Insert a charger cable into the protector from shallow side and pull out from the other side.
2. Pull out string from the reel and insert into the protector (again, from shallow side) and pull out.
3. Using zip tie, attache the end of reel string to the cable right next to the plug of the cable
4. Insert reel into the cable protector. Make sure the cable is on the side with the cable slot.
5. Test the setup by pulling the cable from both side. If you can pull out the cable together with the reel, your cable/plug is too thin - attache a keyring (or anything larger than the hole) to the end of reel string so that your baby can't pull the cable out.
