The door wedge
thingiverse
I'm thrilled with this incredibly handy gadget! After printing it, I placed it under my door, and now the airflow issue is solved - no more shutting the door all the time! I managed to print 10 pieces using PLA material, which surprisingly works just fine for me. Although, I think a more flexible, rubbery material would be an even better choice. Still, PLA gets the job done. The varied colors you see are due to my clever use of almost empty spools, which I joined together seamlessly - not a single piece of waste was produced!
