Earlier, I criticized this model as 'amateurish' and of 'low' quality. However, I have now realized that my printout of the model was incomplete. I printed this model in a single color rather than two colors, which did an injustice to the final output. I have updated our printout with two colors, and I got a perfect keychain, the result of an excellently designed model. I hereby withdraw my earlier review, and I am doing this based absolutely on my free volition.
