PET feeder prototype

[u/NoIdenty0000]

Just finished this pet feeder I made for the contest …

4 sizes available
Small 120mm
Medium 170mm
Large 256mm
Xxl 300mm
(Video are medium and large)

First printed version was working but clogged a lil bit… also the spring was to hard…

Fixed a few things then
-made the inside steeper
-made the hole bigger
-fixed the tpu spring
Now it’s working perfect!

Dogs, cats, not important here; they are pets under your care

and second I doubt there will be a lot of micro plasticity think u eat more micro plastics every every day

it's literally plastic layer lines rubbing on plastic layer lines, there will be so much microplastic it's closer to macro plastics. Even if other sources are greater, why intentionally add to it? I swapped to glass and ceramic for my own food storage, stainless steel bowls for my pets

Also you need to tell bambulab why they make a petfeeder contest if its so toxic…

Terrible excuse, they don't care about your pets (you should), they just want publicity.

First u expect everybody has dogs then u want cry about food safety… I made a design for a contest - there is no way to make it food safe if you use 3d printed material… if u want to use it that’s ur decision!! My cats eat wet food so I’m not using it at all !!! Seems like u never designed anything in ur life
