ULTRAKILL V1 Arm - 1:1 Scale Physical Prop
This is a fully engineered, 3D-printable conversion of the V1 model originally created by @olepatrick1054 on YouTube/Gumroad.

The original asset was strictly a low-poly animation model meant for Blender, so it had zero manifold geometry or internal structure for printing. I took his original files, completely rebuilt the internal geometry, split it into printable sections, and scaled it to a 1:1 human scale (about 650mm total length).

Build Details & Print Settings
Scale: Sizing is necessary. I sized it up to about 650mm in length, but below is the link to my Makerworld print profile if you would like the exact sizing in the image.

Supports: Yes, you will need them for the joint overhangs and the main claw curvatures. Standard tree supports work best - but cleanup is heavy. Leave a comment if you find a more optimized way to print.

Infill: 10%–15% Gyroid is plenty. It keeps the parts lightweight but structurally solid enough for assembly and painting.

Wall Loops: Recommend at least 3 walls so you have enough material thickness to sand down any layer lines without breaking through the shell.

THIS IS NOT A WEARABLE PROP. THIS WORKS ONLY AS A DISPLAY PIECE.

Note: This model is for personal use and prop building. Make sure to credit olepatrick for the original concept shape if you share your builds online!
