A small keyless lock for drawers,cabinets, etc. (or in my case a 3D printer enclosure)
Needed for assembly:
M3 x 10mm bolts with nuts
M3 sheet-metal ring
All the 6 parts are to be made separately and then assembled.
(Although you only need 4 of the parts in order for this lock to work, there are two back plates for better tightening the lock)
