Just thought I'd share findings with my latest prototype for an elephant toy in development.
To facilitate wall thickness in my design, I put a 1mm+ hole in the end where the ear connects to the main body.
However, I was surprised that the ears were heavier than my calculations; causing them to droop when assembled.
Ultimately, it was discovered that the ears were filled unfused powder material! I drilled a hole and emptied the contents out which equalled 3 grams of extra weight on a part that should weigh 5.5g.

Not sure if this extra weight is charged to me upon printing, but I'll be making bigger holes whenever possible from now on Shocked

Happy Fabricating,
