I created the gate latch to incorporate into another Design that is still in work.   I went ahead and posted the Gate Latch Assembly here as a stand-alone design.  The gate latch assembly is lockable.  The initial was designed using Fusion and first printed on the Creality K2 Combo in Creality Hyper PLA, Matte Black.  For the follow-on prints I used the Creality K1C to print the parts in Hyper PETG and Hyper PLA-CF.  If you wish to print this design and you live in an area with hotter temps considered using ABS and ASA filaments for strength and heat resistance.
