This compact and versatile EDC tool is the perfect everyday companion for makers and 3D printing enthusiasts. Fully designed by me and printable in a single piece, it offers a wide range of useful features:

🔧 Bit Storage: Holds up to 4 standard 1/4” screwdriver bits (hex, Phillips, flat).
📏 Precision Ruler: Engraved ruler on one edge for quick, accurate measurements.
🍻 Bottle Opener: Integrated into the bottom for everyday convenience.
🧽 3D Print Bed Scraper: Ideal for safely removing printed parts from the build plate.
📦 Box Opener Blade: The front edge is shaped to cut open boxes and packages with ease.
🔩 Hex Wrenches: Internal and external hex cutouts fit a variety of nut sizes.
🔗 Keychain Hole: Top hole for attaching to a keyring, carabiner, or lanyard.

Lightweight, practical, and packed with functionality — perfect for your keychain, toolbox, or workshop.

I printed this tool using Prusament ASA Jet Black, which is a strong and durable filament — ideal for everyday use.

Please note: ASA tends to shrink slightly during cooling, so the internal tolerances may tighten compared to the original design. 

If you decide to print this tool using a different filament (such as PLA or PETG), keep this in mind and expect probably slightly looser fits depending on your slicer settings and material.

Please note: the model is designed for bits with the following dimensions: 25 mm height, 6 mm width (flat to flat), and 7 mm point-to-point across the hex. Make sure your bits match or are close to these specs for a proper fit.
