I made these to use as mold templates and printed on my Elegoo Mars in Resin. This can be done easily on an FDM printer just used my resin for smoother finish.

the size will need to be adjusted but for the straws I have at home I based it on 7.5mm straw diameter so I hope it is close to that.

If done on an FDM use the below:

layer height: .2
rafts: Doesn't matter
Supports: in the creeper and Tweety is a small rasied area on the bottom so might need them
nozzle: 210
bed: 60
infill: 20%

Used these to make molds so printed in resin for smoother finish.
only did supports for inside creeper and Tweety head to be cautious.
