Pulled from the paid files of Project Abby( https://www.cgtrader.com/3d-print-models/miniatures/sci-fi/project-abby-for-naughty-knights )
This is a free assortment of spikes, horns, tusks, or whatever else you wish to use them as, to modify your builds and models to you heart's delight.
Less demonic in nature, and more techno, they're good for that renegade, but not completely possessed look.
10 different configurations in 3 different sizes.
Supported and Clean version in the zipped file.
Base attachment has small bumps for attaching over pipes or contours. If this isn't to your liking, sand them off to match the receiving surface.
Enjoy!
Best,JBR
