This is a wearable Bomb Devil helmet, inspired by Reze’s transformation from Chainsaw Man. The design captures the sleek, explosive aesthetic of the character — featuring her signature grin with sharp teeth, seamless surface curvature, and tail fuse detailing.

The model is fully wearable, designed to print in modular parts that can be assembled magnetically and glued together. It includes internal space for lightweight padding or straps for stability.

Features: True-to-scale proportions for realistic cosplay use High-polish outer shell suitable for metallic or matte paint finishes Optional modular sections for easier painting and assembly

Compatible with 3D printers with 220 × 220 mm bed or larger Bambu Slicer 0.20mm Standard Setting Magnets needed: 44 3x2mm and 4 7x2mm Size when fully assembled: W 210 × H 290 × D 340 mm The included .3mf file already has all preset orientations and print settings applied. Tip: The jaw prints facing up, which means the magnet holes are perpendicular to the bed—they won’t print as perfect circles. Clean them up gently with an X-Acto knife or slightly widen with a heated tool to fit 3×2 mm magnets, then secure them with super glue. The bomb body front piece will be glued to the jaw, so make sure the magnets in both parts face the same direction. For the back piece, the magnets should be oriented opposite, so they attract the front pieces (body front + jaw). The mesh front part (circular vent with holes) can be printed standing up if using regular PLA, but if you’re using Metal PLA, it tends to string—so it’s better to print it horizontally. To remove the supports, first detach one end, then insert a flat-head screwdriver (or similar tool) and use a gentle rotating motion—like opening an oyster. The supports should release in one clean piece this way. For full assembly details, watch my assembly video @ Allthebuz3D on IG or TikTok.
