haha, this remind me of when i modded my grinder. Its one of those cheap £3 acrylic ones with the storage compartment on the top. i drilled holes in the top, so the grinded bud falls through into the storage compartment, then i made another plastic disc that slots into the holes i drilled, so it falls through, then i clip the disk in and it stores my weed.Still works perfectly to this very day.
