I had a drawer that kept sliding open on me so I decided to make this simple bolt/latch. It prints in three pieces, the latch, the housing and the knob which screws into the latch once it is slid into the housing. I didn't bother cleaning up this print much.

I found that the threads on the knob printed best when the knob was printed upside down with the threads on top. The housing printed best standing up with the latch opening on top and with brim bed adhesion. I noticed a thin layer of material filled the knob opening of the housing but I was able to easily snap it off after the housing printed (not exactly sure where that came from). The latch part can just be printed laying flat (I used ironing on top just for a nicer finish)
