Bring a more authentic, prop-builder feel to your Mandalorian helmet with this functional rangefinder upgrade designed for The Shrike helmet by AlterEgoArmory. Inspired by classic Mandalorian gear and built with cosplay practicality in mind, this accessory replaces the original right ear and adds a detailed, wearable rangefinder in Hasbro helmet style assembly with integrated LED routing.

The design is made for builders who want both visual accuracy and real functionality. The rangefinder arm includes a hidden cable path for LEDs, the ear section is designed for a clean fit, and the finished assembly locks in place with a tight, dependable upward position. It is a compact upgrade that adds a lot of character to the helmet without overwhelming the original design.

Features • Replaces the original right ear of The Shrike helmet. • Designed for a clean, functional Mandalorian-style upgrade. • Internal cable path for LED wiring through the arm and into the helmet. Use preferably AWG26 silicone insulated cables. • Requires only one drilled hole under the ear for cable routing. • Uses a 10x4xID3 bearing. • Tight-fit design that holds the rangefinder in the raised position. • Internal cavity with holes for 2x 5 mm LEDs. • Built for cosplay, display, and practical wearable use.

Print settings • Nozzle: 0.4 mm • Layer height: 0.1 mm • Perimeters: 4 • Infill: 15–25% gyroid • Supports: tree supports • Interface finish: ironing recommended • Materials: PETG, ASA, or ABS for durability

Lens / glass note For the lens area, a flat FDM print can work if printed very slowly with high-quality layers and higher temperature, but the best glass-like result will come from a resin printer. You can also choose to use the design without the glass element if you prefer a simpler build.
