I took mz4250's Darkmantle and pulled the mounting hole up a bit before stretching the tentacle half slightly. I then extended the hole into the head section and added a large hollow cavity to lower its weight. Finally, I increased the width of the tentacles to make them easier to print and to make them heavier.

This is all to allow the Darkmantle to be removed from its base and balanced atop whatever miniature it might be engulfing during combat. The extra weight towards the bottom should hopefully help with balance.

I also fixed the weird boolean thing that happens behind the eyes due to some quirk of mz4250's software.

Instructions included.

I changed the hole diameter to match some clear acrylic rods I have, so if you edit mz4250's clear base for this, you'll need to increase the post to JUST UNDER 3.5mm wide. In addition to height changes needed tor the deeper cavity.
