4 original latches were broken, I tried to make them from different ones - with a larger wall thickness when printing, with a large infill, from PETG and SBS plastics. All broke down over time. I made a spring latch, there is nothing to break in it. need: 4ps screw M4 25 mm - for model Celling mount 2ps screw M4 25 mm, 4ps M4 12 mm - for model Wall mount spring D8~6 mm, length ~ 20 mm Wall mount part names start with a letter W (Wall) Ceiling mount part names start with a letter C (Celling) 4.10.22 Add on Made the TopPlate V2 and Plate V2 details. Now it should be easier to install the latch in place. 02.11.22 New model with vertical wall mount mechanism All details, except for the "PIN" detail, are redrawn. For wall mounting print details starting with the letter "W" (Wall). You will also need two M4x25mm screws and four M4x12mm screws. M4x12 screws will need to be threaded into the "Wwall" parts, screwed on both sides. The "Wwall" part is best printed as in the picture, using supports from the table to keep the round screw holes.
