Intro

A very small bit holder designed to fit on your keyring while still offering a confident, textured grip. This ultra-compact tool holds hex bits securely — tight enough for reliable twists yet easy to carry everywhere. Perfect for quick fixes on the go.

A handy tool to keep on your keyring or in your bag — ideal for quick adjustments, loose screws, or small assembly jobs without needing a full-size driver on hand.

This tool was engineered to hold bits snugly — not loose — so they stay in place during use. It’s simple, practical, and quick to print. If too tight, print the model in 101% or 102%. If the bit gets stuck, use pliers.

Why you'll love it?

• Super-mini size — ultra-compact for keyrings and pocket carry. 
• Textured handle — enhanced grip despite the tiny form factor. 
• Secure bit retention — holds bits snugly in place. 
• Easy to print — optimized for fast desktop 3D printing.

Recommended print settings

• Nozzle: 0.4
• Layers: 0.2
• Infill: 100%
• Perimeters: 2
• Top fill pattern: Concentric
• Bottom fill pattern: Concentric
• External perimeters first (important for accuracy)
• Material: I recommend to use PLA or PETG (see below)

Print with the bit opening facing to the print bed.

Please mind, every filament has a slightly different behavior and every bit varies slightly in size too. So if it doesn’t work in the first run with your filament/bit, please make sure to activate the “External perimeters first” option in your print settings. You also can try to change the size of the print a little bit (e.g. scale it to 101% or even 102%).

Filament recommendation

I used Prusament PLA Prusa Orange to print this model - It works great for this model.
