Model scaled down to 1.5 percent actual size from scan. Printed at 0.2mm layering with defaults plus “supports everywhere” and z-contact set to 0.2 (Detachable), it reliably prints on my Mini. One note is that the antlers and front legs of the deer are very fragile and typically break when removing the scaffolding; recommend working quickly after print finishes with tools to cut away the support material from those parts.
I have also had success with supports from the build plate only (the 8 hour print), with only minor clean-up work needed. This is the pictured print, using PLA Extrafil White; the slightly stretchy nature of the Extrafil PLA let it fill across some voids. While print is messy in some small areas if you don't use “supports everywhere”, my kids still like the Aretmis. For a clean print, definitely go with the supports everywhere option.
