My DM was looking for an aggressive-looking wolf model. The wolf model in Harrison Baere's collection seemed too calm, so we opted to try to shrink down Harrison Baere's winter wolf model instead.
I thickened the wolf model using Meshmixer, with the help of this guy's tutorial: https://www.youtube.com/watch?v=sge8029CucM
I fixed some mesh problems with Netfabb (https://service.netfabb.com/service.php). This is a fantastic help for fixing mesh problems, it seems.
I added a base from "beard_second"s thingiverse collection: https://www.thingiverse.com/thing:2577122
This process allowed the model to be reduced to 28mm scale and still be strong enough to print and clean. The results were everything I hoped they would be.
