Hammy3DPrints Battery Cap Removal & Installation Tool for SRO Red Dot | BROS Compatible Nylon Tool

Overview

The Hammy3DPrints Battery Cap Removal and Installation Tool is a purpose-built nylon, Multi Jet Fusion (MJF) tool designed to help you safely manage the SRO red dot’s battery cap. By combining high-strength nylon with thoughtful geometry, the tool aims to protect the optic body and glass from scratches during removal and reinstallation. It’s compatible with SRO setups both with and without the BROS accessory, offering a flexible solution for frequent cap maintenance.

Crafted with a tapered midsection, the tool positions itself nearly perpendicular to the SRO. This design characteristic can make cap engagement more controlled and comfortable, especially when working in tight spaces or at an awkward angle. The result is a handling experience that feels steadier, with less risk of sliding or misalignment during use.

Why it matters

Because it’s 3D-printed from nylon, the tool is forgiving in comparison to metal-on-metal contact. This means the risk of marring delicate surfaces—such as the optic body or glass—may be lower when you’re maneuvering parts in tight confines. The tool’s neck length is intentionally designed to accommodate BROS, expanding its versatility across common optic configurations.

How to use

Follow these practical notes to get the most from the tool without over-torquing:

• Push the tool into the battery cap while you twist to engage.
• When re-tightening, twist until snug and stop—this is a plastic tool, not a lug-nut substitute.
• Ensure you’re working with a clean surface to minimize slipping or debris causing contact.
