Perhaps a derivitave designed from scratch. The other saftey latches I've printed are not long enough and seem to break too easily. This model allows for thicker cabinet walls. Designed weird for easy flex and guaranteed* catch. *Item not guaranteed :)Print (30% infill worked for me), no raft necessary for delta model. Test for the best spot to mount the latch. Please do not rely on these items. You are the best saftey for your child.
