OSRS slayer helmet

I exported the obj of my character wearing the helmet using the Runelite Model Exporter plugin. After chopping off the rest of my character, I had to make a bunch of edits to the mesh so it could be solid (video games don't require objects to be solid or walls to not have 0 thickness). As such, there may be some small differences especially around the spikes as I pretty much had to redo those.

You will definitely need supports for the bottom spike as well as the parts on the side that go out horizontally. I printed it with 15% infill (probably doesn't matter), 0.2mm layer height, 3 walls, automatic supports from the buildplate only. Printed on a Prusa Mk4 with 0.4mm nozzle and used the input shaper structural profile with the modifications stated.
