Hey, This is a handle/clasp/lid thingy I made in order to fix a flimsy handle that was already there. It saves on filament and prints quickly (costs about 30 cents~). Much more durable than the original piece as it is thicker. Not super difficult to get into place and won't randomly come out. It also makes a nice clicking noise when you open and close it which is a plus. Stays in place even when tub is exposed to wear and tear/violent shaking etc. Hope it helps :)
The part which it is fixing is very weak and commonly breaks where it goes through the holes in the tub. This is much more thick there which means it is significantly stronger. If it were to work better, that would come from making one side a tiny bit longer but that would make it more difficult to put into place. It could also benefit from a slightly shorter clasp.
