About this 3D model
Children safety guard for a round door knob. Print the piece twice. Secure the pieces with tiny zip-ties, and snip the excess. This design has kept one tenacious child safe for a few years, but no guarantees it will hold all escape artists. Easy to remove by cutting the zip-ties.
