I really liked this poop drawer but found it impossible to screw in the handle because of the limited space to work with inside the drawer and the fact that you're screwing in at a 90 degree angle.
So I merged the handle with the drawer in the slicer and thought I'd share my model in case it saves anyone else a few minutes.
Everything else can be used from the original model, just print out my modified drawer and you're good to go.
The author remixed this model.
Handle has been merged with the poop drawer so it doesn't have to be screwed on afterwards
