Blockade for the old drawer

Designed to protect old type drawers from falling out of the cabinet. It locks and unlocks easily. Attached files are for the left side protection, to make right side just make a mirror of the left side.

files:
stencil - this is to put on the edge of the drawer for easy drilling for mount of the back piece
back stl - main part assembled to the drawer (holes for 3mm bolt)
bar - part blocking the drawer from falling out by colliding with the blockade on the cabinet (has a hole for 3mm bolt, better to use together with a washer)
blockade bigger and smaller - parts that should be placed on the cabinet, might not fit your needs, it just needs to be something to collide with.

3mm bolts for the wood and a 3mm short bolt with the washer required for the assembly.
