Door Knob W/ Special Key

thingiverse

Safety door knob with key I used this to keep my kids out of the laundry room. The "Knob" inserts into the original knob with the long rod (US) I assume most countries are the same. Please do not use this on any emergency exits as it could cause issues getting out if the material melts. Only use this on rooms that are not common use like laundry rooms or closets. Please use common sense. Here's a link to the magnet I used: https://www.amazon.com/gp/product/B089CPXQQG/ref=ppx_yo_dt_b_search_asin_title?ie=UTF8&psc=1 If you're outside the US please drop the country you're from, I always enjoy seeing the different parts of the world my designs reach.
