Detergent powder dispenser

So, my mom wanted one of these, and these do exist, but all of em are just too expensive (minimum 100$). So yk, I built one myself that I can 3d print (once I get my printer :P). So basically, its a storage box, or as I like to call it, pod. It has a hole at the top with a lid (lid has proper ergenomic handle). It has another hole at the bottom with a funnel connnected to it, for easier pouring. Then It has a joint/hinge which when rotated, the bottom hole can be covered and uncovered for stopping and startting the flow of powder. ALSO ALERT, this isnt for liquids, its for dry powder, I didnt design it to be water tight.
