We should ALL be donating blood, but more importantly is when we need blood ourselves.
If you're ever in an accident, carrying something like this, or at least having it on your bag, helps medical professionals to administer the right blood type quickly.
I've used a modifier shape to expose the honeycomb infill for an extra twist, with ironing turned on for the smoothest possible surface finish.
I printed in translucent glitter red, with solid white, both PLA.
I'll be working on other blood types soon.
Thank you and stay safe.
