Peugeot Paris Wooden Pepper Mill Assembly

I've disassembled it initially to clean the inside because I was grinding things that were softer than peppercorns (bad idea), and it ended up clogging up inside. This video shows the reassembly process. FORCE is required for the following 2 instances: 1. snapping back the bottom part back into the white plastic. 00:52. Was too difficult to do this only by hand, so off-screen, I've used a flathead screwdriver to concentrate the force on the tab into the white plastic. 2. and then screwing the bottom part 04:31(unscrew in the other direction for disassembly)
