Three-Dial Combination Bolt Latch
A print-in-place combination sliding bolt: three 26 mm dials must each have their gate notch facing the bolt before its tapered fences can drop in and the 5 mm-throw tongue can retract. The 112 x 48 x 4 mm base plate screws to a cabinet, gate, locker or toolbox with four M4 screws (4.5 mm clearance holes on a 102 x 34 mm rectangle), and the whole thing — plate, three dials and the bolt — prints as one assembly with no springs, pins or fasteners.
