XXXS Bit Tool - Super-mini & Super-grip

Intro

A super-mini tool designed to hold standard hex bits with exceptional grip and control. Its compact size makes it perfect for tight spaces, keychains, or everyday carry in your toolbox — yet it still offers a confident, textured grip that feels great in hand.

Ideal as an everyday carry bit holder, toolbox addition, pocket tool, or tiny helper for quick fixes. Its firm grip on bits means you can twist with confidence without worrying about slips.

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 or push a nail through the hole on the top.

Why you'll love it?

- Ultra-compact size — tiny footprint for keyrings and pocket carry.

- Textured handle — improved tactile grip for better control.

- Secure bit retention — holds bits tight for reliable use.

- Easy 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%).
