Solid funnel to avoid spreading goods all over the place while pouring Cerial, Coffebeans, Cornflakes into storage boxes. Use this solid goods funnel. Easy print no support. Recommend to use FDA certified filament like PET for printing. Anyway PLA will do the job as well as long as you have no focus on FDA regulations.
Funnel on the pic was printed with 125% printig speed. Better use lower speed to improve printig quality.
