I really liked the design by kpimmel.
I removed the numbers which made it easier and faster to print.
It's now better orianted for printing
Fixed the size as it was too small for standard regular cat food/treats (120% the original), left the opening the same.
The lighter it is the easier it is for the cats. Would recommend max 2 walls on 0.4 nozzles, I use a 0.6mm nozzle so I did 1 wall at 0.8mm line width.
10% grid or gyriod infill is sufficient.
Final print was 15 grams.
Can be printed at any layer height.
No support.
Cooling turned off on me, that's why the top looks a bit messy. It should print fine for you.
