At least when I printed it, it wasn't very functional. The latch doesn't seem to have any sort of locking mechanism and therefore made the hook sort of useless. This became more evident when scaling the model down. It might work better at larger sizes.
hey. this was a supporting remix to show what I was talking about in a comment.
print the knurled knob from the original to make it make sense.
it’s already pretty small. any smaller and the threads are likely too weak to print right.
