Special thanks to @schtiewie for sharing original model with us.
UPDATE: 29.09.2025 - I have added bottom jaw in one piece together with splited parts and connectors.
You will also find .3mf file with all plates of bottom jaw included.
The lower jaw is supposed to be screwed together with upper part with m12 screws or any similar.
For this purpose I uploaded screw, cap and washer to be printed.

Holes are made in lower part, and also the upper back parts are reuploaded in the folder.

HINT: In case you want to add this to previously made mask - drill the holes.
Have a good Halloween !
UPDATE: 30.10.2024 - I added separate models for the right antler to avoid having to use the "mirror" option in the slicer.
I also updated the "all connectors" stl file.
It was pretty hard to connect the parts together so they will fit exactly on the spots, so I have made holes in each of the elements, marked them with ABCD's and created connectors for them to be printed along with model.
Also I rotated the model pieces correctly so they will now be in BEST possible position to be printed.
From the original description:
Scale it properly!
For 57cm head circumference 103% scale up gives a snug fit, 104-105% should work better
For 58cm head circumference 107% scale up should work well
For 59cm head circumference 110% reported to fit well over a head
Remember to scale the connectors the same!
There are octagonal alignment slots and through-holes for easier antlers alignment and attaching. The 100% scale model should be fine to fit M12 nut inside the antlers base, and M12 bolt underneath the mask rear part.
There're also antler “base” bumps on the rear side of skull to add thickness and make it easier to mount the antlers (should work both as glue-in or bolt-on).
Hope this will help you guys and happy cosplaying!
If you would like to support me - you can buy me a coffee :)
