I made a lockable door bolt latch that is bulky by design. 

Print with your desired parameters. 

The wings on the slides are blank so you can add any holes for screws, washers, etc.

Parts can be printed without supports.

----------------------------------------------

Main slide is 70mm L x 100mm W x 35mm H, Recommend print on SIDE.

End slide is 30mm L x 100mm W x 35mm H, Recommend print FLAT.

Bolt hole for lock is 10mm Diameter.

Bolt handle can be friction fitted into bolt, use glue if needed.
