this is inspired from a Reindeer Band Saw Cutting Project, an inspiring video from Workshop Companion.
Support under the belly is your friend if the printer do not handle the bridge.
Legs are cute but small, ifd you experience detachment issues, use brim or better a couple of layers of raft.
In case you do not want to mess around with brims/rafts, I uploaded a version that is 133mm tall with an added layer of support under the legs that you may cut?strip away after print. (see picture - the gold reindeer)
