Summary

I Remixed @stunner2211 's model, it is now directly printable as a Keychain. I have made 2 and they turned out beautifully. Please use supports. Thank you @stunner2211 for the Lovely model. I scaled it up as the original file was loading tiny, no details have been lost, reduced the mesh size so i could edit it on Fusion 360. 40% Infill gives it good weight.

Post-Printing
